Dopovidi, no. 3, 1961, 325- 327 TEXT: An experimental study of corrosion fatigue is described. The experiments showed that the reduction in fatigue strength can be related exclusively to the cathode process and the absorption and diffusion of hydrogen involved. The specimens were made of steel 45 and had a diameter of 20 mm. The corrosive substance was a 3% NaCI-solution in water (similar to sea-water), which was in- troduced through tube 1, separator 2, and tube 3 of Fig. 1. The anode was platinum wire 4, the cathode - the specimen. The current density varied between 0.007 to 6.2 xnp/dm2.

The experiment led to the following conclusions: 1) The increase (within certain limits) of the current density with cathode polarization, leads to a decrease in the in- tensity of the anode process, as a result of which the endurance limit o, increases. 2) With optimum current-density (under the VW 2), given condition 0 DC 0.15 amp/dm the anode process ceases altogether; a -~ reaches its maximum value, which is by 1W~ lower than the endurance limit in air ol-i. This can be explained by the presence of the cathode process, and by adsorption and diffusion effect. 3) An increase in the current density above the optimum value, leads to an intensification of the cathode process and to a decrease in (Y-14. 4) Cathodic protection cannot, even wita optimum '1 choice of current density, completely reestablish the fatigue-lim- its of the metal.

High speed cutting conditions Increase, and force cutting conditions re- duce the endurance limit, as compared with conventional turning in both air and a corrosion medium; this occurs to a particulafty high degree in the latter.case. Grinding of the parts after turning under different cutting conditions does not eliminate the effect of preliminary machanical treatment upon the endurance li- mit, i.e. an effect of technical prehistory Is observed. This effect upon the fatigue strength of steel is higher in a corrosion medium than in air. Abst cterls note: Complete translation] R rd Vi S/123/62/W0/023/002/008 AOo4/Alol AUTHORS: Babey, Yu.

Dopovidi, no. 4, 1962, 461-464 TEXT: The mechanism of fatigue failure of steel under the adsorp- tive effec-c of the riiiedium, is considered. The external media may .aave the effect of either lowering, or increasing the fatigue stren"th of steel. Owing to the fact that cracks start developing at the surface of specimens (in the fa-cigue process), the lifetime of metals under cyclic stresses depends considerably on the exter- nal medium and the surface state of the specimen. A figure shows the results of investigations (conducted by the authors) on the ef- fect of Borislav oil on The endurance of steel 20X (20hli). Thereby, the lifetime of the specimens increased considerably under overloads as well as the endurance limit. Other experiments (oy various in- u vesligators) have shovm that surface-active media which facilitate Card 1/3 S/021/62/000/004/007/012 On the mechanism of fatigue failure ... D299/D302 the formation of slip lines, cause a lovierint; in endurance. With respect to fatigue failure, due -to electrochemical corrosion, it vias found that if the cyclic stresses are -Large, the fatigue failu- re is related to cathode processes; in case of small stresses, it is related to anode processes. The media which most commonly inter- act witl~ steel, are fusible-alloy melts which are adsorbed. After adsorption, dissolution and diffusion processes take place. The ki- netics of these processes depend on various factors (composition of alloy and of steel, ratio of melting points, etc.). A -L"i6ure shovis the resuits of experiments on the effect of mercury on the enduran- ce of steel Y8 (U8). Here, too, it was found that large cyclic strea- ses lead to an increase in lifetime, whereas small stresses, close To the fatigue limit, facilitate the formation of slip lines. The use of melts which form (in the surface states of steel) intermetal- lic compounds, is very promising. Thust by using the melt Pb-Sn, it 'ible to considerably increase the endurance of steel. Under- is possi the adsorptive effeci of the medium, a kind of inversion of the en- durance curves, takes place; thereby the lifetirrie increases and the fatiggue limit decreases. In the case of melts, interacting with steel, the converse happens: The lifetime decreases and the fatigue Card 2/3 S/021/62/000/004/007/012 On the mechanism of fatigue failure D299/D302 limit increases. In conclusion, a thorough knowledCe of the effects of the medium, under cyclic stresses, is needed for design of machi- ne parts in many branches of industry.

The singling out of hydrogen ions can take place at a sufficient cur- rent density of cathode polarization from an external voltage source, or at a sufficient difference of potentials between the micro-electr%Klc *eQtjonz of the metal surface, Both qa*eu were atudled and the nature of metal d0f6ruip-tion in -the process of hydrogenization was determined. The following 3 cases were in- vestigated: 1) cyclic bending below the yield limit; 2) uni-axial tension be- Card 1/3 S/676/62/009/00()/006/010 On the possible appearance of....Z A006/A101 yond the yield limit; 3) alternating bending beyond the yield limits. The cor- rosion medium was a 3,r~'Y-solution of sodium chloride; current density was 0.0,7 - 15 amp/dm2; the specimens were made of pre-eutectoid steel. An analys1s of the reoultu obtained leads to the following conclusions. In all types of deforma- tion, polarization from the external power source causes a decrease in the mechanical properties. For case 2 and 3 the neutral corrosion medium reduces these indices even without polarization from the external source. The dependence curves of mechanical characteristics show, for all the cases, a maximum in the range of lower current densities. An increase in the current density toward both the anode and cathode reduces the indices of mechanical characteristics, which is exDlained for the former case by intensified anodic processes and for the latter case by hydrogenization of "he metal, entailing hydrogen fatigue and brittleness. The inclination of the curves Indicates the predonninance of either the anodic or cathodic proccos, or their equilibrium. As the deformation in- tensity increases from the first to the third case, the maximum is shifted from the anode to the cathode. This indicates an increasing difference of potentials bet,.,,,een the micro-anodic and micro-cathodic sections of the steel surface. As a reSuit, in the third case conditions are developed for the hydrogenization of Card 2/1, 816761621009100010061010 On the posoible appearance of'...

The purpose of the present paper was to determine the effect of ro- smelting on contamination of ShKh15 steel with oxides, sulfides, and air bubbles and the corrosion resistance and corrosion-fatigue strength of this steel, in both the perlite- ferrite and martensite states, in 3% sodium chloride.

Smelting increased the corrosion-fatigue strength of ShEh15 steel by up to 40% in the martensitic hardened condition and by up to 20% before hardening. i -However, lowering the quantity of impurities below a certain value did not affect the I --corrosion and corrosion-fatigue strength of the steel. "The thermal treatment was I i . carried out by F. P. Yanchishin (Cand. Tech. Scl.) and Eng. K. P. Tabinskiy.
