TITLEs Examination of mineral oil additives as seizing protectors for steel PERIODICALt Izvestiya vysshikh uchebnykh zavedeniy. Neft' i gazt no. 4, 1961, 63-67 1 TEXTs In this article, a new method of determining the effect of additives on seizing and welding through friction of metals is described. This method is based on a continuous change in the sliding speed over a wide range. The tests were carried out on a four-sphere device with automatic recording of the friction coefficient. The speed variation of the upper sphere from 0 to 19-5 o103 rpm was accomplished by a specially constructed appliance. The spheres had 12.7 mm in diameter and were made of UJX6 (ShKh6) steel hardened to 62 R 0; all the experiments were carried. out at 200C. The naphthenic paraffin fraction of the oil MC-14 (MS-14) was used as a base oil, with the following additivesi 1) 0.15 mole/l dibenzyldisulfide, 2) 0.05 mole/l 1-trichloro-5-methylpentane, 3) 0.05molell Card 1/2 22282 8/15 61/000/004/003/009 Examination of mineral ... B126YB219 dibutylester of methylphosphinic acid, 4) 0.05 mole/l tri-(trichloro- ethyl) phosphite. With naphthenic paraffin in oil, seizing occurred at a considerably higher speed and at low load; an increase of the load at relatively low speeds initiated seizing. When dibenzy1disulfide was addedg seizing occurred at sliding speeds that are between those at which seizing is initiated and those at which repeated and very intense seizing occurs with naphthenic paraffin oil. A trichloromethyl additive had a slight effect at low load and became more efficient on increase of the latter; the friction coefficient remained low up to the limiting speed; a further increase in load reduced the effect of the additive. The ester of methylphosphinic acid affects the seizing loads very much. Organic phosphorus compounds are very efficient and have the ability of modifying the friction surfaces; the addition of chlorine derivatives considerably increases the already high critical values of these additives. These results show that the new method facilitates the examination of the efficiency of additives. There are 4 figures. V I ASSOCIATIONs Akademiya bronetankovykh voysk im. I. V.

TITLE: The Anti-Wear anaAnti-Frictional Properties of Hydrocarbons (0 PERIODICAL: Khimiya i tekhnologiya topliv i masel, 1961 No. 3~ pp. 48-54 'A TEXT: Four-ball machine friction and wear tests were made on the following hydrocarbons and mixtures of them: Tetracosane; 7-hexylootadecane; 1.5-dicyclohexyl-3-heptylpentane; 1.5-diphenyl- 3-heptylpentane; 1.1-diphenyldodecene-1; 1.1-diphen,71dodecane; cyclohexyltetralin and dicyclohexyldecalin. The balls were 0.5" diameter of ball-bearing chrome-steel hardened to 62 Re. Atmos- pheres of argon, air and oxygen were used in the tests. All the tests were carried out for one minute at a sliding speed of 23 cm/sec, in the tests with argon and oxygen the gas was blown through at a rate of 12 litres per hour at a temperature of 100 1 10C, After each test the load was increased and the balls were rotated to present a fresh wear-surface but the lubricant was not changed. Tests were made below, at and well-above the Card 1/4 89126 S/065/61/000/003/001/004 E194/E284 The Anti-Wear and Anti-Frictional Properties of Hydrocarbons seizure load. The results are presented in the form of log/log graphs of wear against load, wear being assessed by diameter of wear-sear. The tests in argon atmosphere display considerable variation in seizure load and shape of wear curve. In general, however, in argon the seizure loads are low and the wear is small at loads below the seizure loads. The seizure is easily broken down. The test results of hydrocarbons in argon are similar to those observed for low-sulphur lubricating oils. The behaviour observed is attributed to the presence of traces of oxygen or oxygen compounds in the hydrocarbon that are capable of replacing the oxide films on freshly worn metal surfaces provided that these are not produced too rapidly. When argon is replaced by air the seizure load rises because both metal and hydrocarbons are more easily oxidized. In an oxygen atmosphere the seizure loads are still higher and the wear curves rise smoothly. These smoothly rising wear curves are most typical of the easily oxidized and relatively low viscous hydrocarbons such as cyclohexyltetralin. The more viscous and less readily oxidized hydrocarbons often have Card 2/4 8912 S/065 61/000/003/001/004 E194/E284 The Anti-Wear and Anti-Frictional Properties of Hydrocarbons a step in the wear curve, presumably because as the viscosity increases access of oxygen is hindered. However, in an oxygen atmosphere the graphs of wear-sear diameter against load lie within a very narrow band for a wide range of hydrocarbons including not only those tested but many others besides. At loads below the seizure load the wear is often heavier in oxygen thar. in air or in argon and this is attributed to oxidation of the steel during friction. Combined oxidation of steel and hydrocarbon under heavy friction conditions occurs during the exposure of fresh metal surfaces in the presence of frictional heat. The conditions are quite different from those in normal oxidation tests. The results show that molecular oxygen and organic sulphur compounds which react with steel act as anti-seizure additives and as substances which increase the chemical wear of the steel, thus behaving like extreme pressure additives. The separate and combined influences of dibenzy1disulphide and oxygen as extieme pressure additives are described. The main conclusions of the article are that the anti-friction and anti-wear properties of a Card 3/4 89126 S/065/61/000/003/001/004 E194/E284 The Anti-Wear and Anti-Frictional Properties of Hydrocarbons large number of hydrocarbons are very similar in an oxygen atmos- phere. Friction and wear tests with steel balls and hydrocarbon lubricants take place in the presence of oxidizing substances which can have an important anti-seizure effect comparable with that of sulphur-containing extreme-pressure additives. It is claimed that individual high molecular weight hydrocarbons can be used as model substances for the study of anti-wear and anti- friction properties of low sulphur lubricating oils.

TITLE- Method for studying rheological (viscous) properties of polymer solutions and melts PERIODICAL: Zhurnal vsesoyuzetogo khimicheakogo obshohe3tva Imeni D. 1. Mendele- .yeva, v. 6. no. 4, 1961, 417-421 TEXT- A short review of methods for studying rhoological :properties of polymers by investigating viscosity oharaoterlation of solutions or melts is given in the present paper. After discussing principal aspects for these methods, capillary and rotational viscosimetry is described. Some niw testing methods and devices developed in the Institut neftekhimich*akogo sinteza AN SSSR (Institute of Petrochemical Synthesis of the Academy of Sciences USSR) are also presented. Viscosity is expressed by Newton's equation as % - ~ D (1) ( t - shear stress, D rate gra4lent). Rhoological characteristics of fluid systems were determined by the form of the fluidity curve T w f (D) and the values of the parameters.

Two types of visoosimeters were generally used, viz., capillary and rotational viscosimeters. The latter are especially convenient for reat D values. Capil ary viscosimeters operate in the range of D w 10-2 _ log spc, and T - 10 - 10 dyne/cm2. To avoid "outlet effects", devices with two capillaries of different length but equal diameter were used. Constant pressure Is secured by a weight pressing on a piston which floats on thepAymer syst,~m. Compressed gas or extruders can also be used to effect the pressure. In the Institute of Petrochemical Synthesis a load-type mioroviacosimeter (Fig. 1) is used for polymer melts, a gas viscosimeter with constant pressure for melts and concentrated solutions of polymers, and a spring viscosimeter with variable consumption and pressure for solutions CAKS-2m (AW-2a) type] and melts [AKS-5 (AKV-5) type]. A device Identical to the visoosimeter in Fig. 1 was developed by 1. A. Marakhonov in the NIIPPlastmass (Lertingrad). Small amounts of the polymer can be investigated in this m1crov1scosimeter. The gas capillary viscosimeter contains several cylindrical removable reservoirs of different volume with floating pist6ns, The latter are connected to the manometric panel at one end, and at the other to the pressure regulator, manostate and cylinder with inert gas at 150 atm pressure. Also a set of calibrated cylindrical Card 2/8 28937 3/063/61/006/004/004/010 Method for istudyirg rMo~ogioaj ... A057/A129 capillaries of different le"gth and diameter in used with the vigoosimeter. All the three types Of viscOBIMOUM Mentioned can be used up to 350 C. Rotational viscoulmeters can be used in this determination of relaxation and elastic charac- teristics of polymer systems for studying the Weinsenborg effect or the estima- thn of the transitions om elastic deformations to fluldity. On these devices the intervals of D - 10.1 to jo5 zoo and T - 10-4 to 101 dyne/=2 can be measured. Generally devices with coaxial cylinders were used. Many modern rotational viscosimeters have electronic mechanisms for registration and regulation or programmed changes of D. A viscosimeter of the cone-plane type (Fig. 2) was developed in the Institute of Petrochemical Synthesis for investigations of concentrated solutions or malts of solymors in Inert gas atmosphere or high vacuum at temperatures of up to 300 C. Ono friction surface is the bottom of the rotating ouP 4 and the other the plans of the cone 3. The rotation of the latter, effected by the polymer 5, Is controlled by tonsiometrio or inductive gages. By means of a servo mechanism (which controls the hydraulic drive 10) chapgos in the rate of rotation of the cup 4 can be programed. By a quick stop of the latter the relaxation of stresses can be0determined. Some typical curves obtained with high-pressure polyethylene at 220 C are shown In Fig. 3. Curves OAB demonstrate the dependence of the shear stress on deformation (diagrams 1-4; Card 3/8 28937 P/063/61/006/004/004/010 Method for studying rhoologlaal A057/A12q deformation rates 0.75, 2.1, 2.8 and 21-soo- respectively).

The orientation of the lubricant layer on the surface was proved by the IM-,3 (EM-3) electron microscope. Conolymer 60-40 and polycaprolactam were used for the study. Commeroial oii 20 (spindle oil 3), and commernial oil 45 (ma,,,hine oil C (S)) were used an lubricants.

The internlapar spacing d for the electron diffraction patterns was calculated from the equation rd- L4. It proved to be in agreement with the data of Ref. 1~ A 15-day storage of the sample in a chamber free from dust showed that the point reflexes did not disappear, i.e., the lubricant was not absorbed by the resin. The point reflexes disappeared on heating and disorientation set in. At 30-400C the electron diffraction -)attern: corresponded to -a crystalline substance, and at 900C it changed into that of an amorphous substance. The critical temperature at which disorientation sets in was found to correspond to the yield point of the polymer concerned. The carrying capacity was determined by A. A.

The plastic material is applied to one of the end surfaces of a thin-walled cylindrical tube, and its friction is determined with a metal surface. The moment of friction is determined tensometrically. The resistance of caprone and Fluoroplast-4 to wear by 40X (40Kh) steel was established by determining the friction coefficients. Results showed that the friction coefficients Increased with time, then slowly dropped, and finally remained constant. This course of change can be explained by an increase in temperature of the contact surfaces. There are 3 figures and 3 Soviet references. Card 1/1 VINOGRADOV2 G.V.

An important function of the lubricant is to modify the wear products (metal particles) adtbat not only are friction and wear of hardened steel in their presence greatly reduced but also that the wear products themselves become able to act asmanti-scuffing additives in the oils. The experimental data presented is of interest in connection with friction and wear of cermets, combinations of lubricants and certain metal powders, and the interaction between lubricant and.wear products.

The frictional elements can be thermo- statted or operate 'd in a controlled atmosphere. Machine MT-3 is used for high speeds (up to 20 000 r.p.m.).

The following conclusions have been drawn 'from published work carried out in this ser*iea of machines. Under-severe conditions the lubricating properties of refined naphthenic oils depend mainly on viscosity, The presence of oxygen or oxidation products greatly improves performance under boundary lubricationicanditions and can help to prevent seizure, An important functioA of lubricants is to deliver oxidants to the friction zone, and this is why seizure may be more catastrophic in oil bathe than with thin film lubrication. Studies have been made of the.modes of action and limitations of sulphur-, chlorine- and phosphorus-containing additives, of changes in the metal surfacest of the effect of additives in modifying wear debris# and of'the effect of soft and hard particles suspended-in the oil. Studies have been made of various salts as lubricants. The mechanism of abrasive wear has been studied., There are 5 figures and I table.

Hole glycerin proved best, since the diameter of the depyession did not increase and the surface of the plastic balls remained smooth over the total load range, even for 5-06 hr. The anti-wear and anti-friction properties of glycerin for the pair steel-plastic may be ascribed to modification of the steel surface (regeneration of the oxide layers and formation of ferrous glyceratea).

The dielectric constant of "Solidol" fell with increasing Particle orientation, but there was no orientation effect with grease 201. Conclusions: The effect of orientation on the dielectric prope!rties can be studied with solidified oriented structures of a disperse phase containing Anisodiametr-ic particles. In the case of non-aqueous systems containing a hydrophilic disperse phase, 6 and tandrare strongly dependent on f in the fudi9frequency,:range. This is attributed to electrical polarization due to interfacial ion transfer, i. e., along the particle surfaces of the disperse phase. The relaxation time, which was found to be of the order of 10-T sec, is the most important quantitative characteristic of surface polarization. Non-aqueous systems in which electrokinetic effects are produced by an interfacial double layer, display surface polarization and varying dielectric characteristics.

The good reproducibility of the calibration curve when the experiments are re- peated, as well as the fact of the energy of activation being almost the same both at the limit of resistance and when the flow-becomes stationary, lead to the conclusion that the change in structure is reversible and un- attended by any destruction of the macromolecules.

The experL- ments were conducted on a four-ball machine. Variations in the oxidative activity of the ambient gas phase were achieved by conduc- ting the experiments in vacuum. in the air, and by blowing oxygen at the rate of 12 1/hr through the lubricant in the four-ball chamber. In some experiments, varying amounts (0.5-3%) of isopropylbenzene hydroperoxLde were added to the lubricating fluids as the oxidation initiator. The dependence of the wear on the load, frLction-vs.- time diagrams, and dependence of the friction coefficients on the load were obtained for temperatures of 50, 120, and 200C. It was found that the oxidizing agents and easily oxidizable hydrocarbons exert the same effect in polysiloxane fluids as in hydrocarbon lubricants, namely# a decrease in seizing, which becomes degenerated and is terminated.

Triphenyl phosphate (1), dibenzyl di- Isulfide (2), sulfole (3), isohexylthiophane (4), a-butylthiophene (5), 12-acetonylmercaptothiophene (6), 2-mereapto-57ethyl-3-thiophene- acid (7), 2-mercapto-5-ethyl-3-thenyledenimine (8), 2- ,benzim.idazolethiol (9), N-methyl-2-benzimidazoletl)iol (10), and ,chlorinated paraffins (C2511SIC1 to C25114OC112) (11) were used an additives. The additive concentration was taken as 1% sulfur in the lubricant for sulfur-containing additives and 0.22 phosphorus for triphenyl phosphate. The additives did not dissolve completely in the polysiloxanes, but formed suspensions. It was proved that the highest activity of the additives can also be displayed in the emulsified or suspended state. The experiments were carried out on' a four-ball apparatus at 50C and a.t a sliding velocity of 23 cm/sec by a step-loading method with no change in the friction surface. To determine the effect of the nature of the polysiloxane on the effectiveness of the additives, polymer 3 was tested with additives, 2, 3, 7-9, and polymer 2 with additives 1-3, 9, 11. The antiwear property of polymer 3 was not improved by any of the additives. Only chlorinated paraffin improved the antiwear property of polymer 2 for I_ _ , Cord 2 / 4 ACCESSION NR: AP4043281 small loads. Additives which are highly effective in hydrocarbon lubricants in respect to preventing seizing of steel are less effective in polysiloxanes. Their activity sharply drops in the transition from polyethylsiloxane to polymethylsiloxane and drops even further in the transition to polymetliylphenylsiloxane-whicit oisesser, thermooxidation stability. It was proposed that in the p decomposition of widely known additives-which determines their effectiveness against the seizing of steel, a chain reaction is ini:tinted in which the basic components of the lubricating oils take t; part, The effectiveness of the additives against seizing decreases in lubricating media with increasing stability,in respect to reactions with free radicals. The ineffectiveneas of additives in the poly- mcthylphenylsiloxanes can be explained by this phenomenon. It is noted that the activity of certain polysiloxanes as lubricating media must be taken into account in studying *the additive action ajzdnst the seizing of steel in polysiloxanes. On the basis of comparison Of the experimental results for solutions of additives in polyethyl- siloxane in air and in vacuum, it was concluded that molecular oxygen influences the effectiveness of the additivea'in different ways.

The typical soap-oil greases had a specific !resistance of 3.010 - 1014 obm/cm (U highest., Ca lowest). Upon applying a constant' electric field,, the specific resistance of these system will increase with times Change of the charge sign of the electrodes will cause a sharp drop of specific irecistance. These effects were connected with various -nifestations at the ~electrodes (e.g. electrolysis,, and gas bubbles). As a result of electrolysis,, water gradually disappears from the system., affording electrokinctic phase changes At the surface of the negative electrode a layer of the dispersion mediun is forxed, Simultaneously the structural framework is compressed at the positive electrode andi. the thickness of the boundary layer increases with the duration of electric field action. A drop of specific resistance occurs as a result of grease deformation. :Upon abrupt stopping of the plastoviscometer-condenser., a sharp change of specific resistance is also registered. Under the influence of the force of inertiap ielastic deformation of the structural framework takes place. This may pull the material off the rotor surface. Upon return of this framework., the material will ~Jagain make contact with the rotors, This explains the rapidly alternating increase Icand decrease of specific resistance vpcm sharply decelerating the systems r ---- - ----- ACCESSION XR: AP4037175 Moisture plays an important part* Orig. art. has: 3 figures* ASSOCIATION: Institut obahchey i neogr=icheskoy,kh4mJj AN UkrSSRv,Xi*v(r=titUt8 of General anl Inorgenic Chmistry AN UkrSSR) SUECITTM: O10ct62 ENCL* 00 80 CODE: GCp EM NO FW SOV: 007 on=: 003 3/3- LEONOVp A.I.; MALKIN, A.-fa.; LJI~~A4Pqj G.V.
