The equation is based on the assumption that the activity of the deposited metal is a function of the current, due to the diffusion of the metal in the hard electrode. The equation thus obtained is identical with the Geyrov-IlIkovich equatioon. ,)AIJ 7-. c:~,b_V?ey Card 1/1 MICHUMO I D. I 1-V:U,-C)V, B. F., an3 DELDMSKIY, Y.

The reduction polarograms were recorded on an LP-55A polarograph at 2400C, and the half-wave potentials of the reduction of the oxides were determined: Ei/2 was 1.1 V for La203, 1-08 V for Gd203, 1.03 V for Y203, 0-9 V for Ce02, and 0.4 V for EU203. Thus, the deposition notentials differed appreciably in this fused electrolyte.~ The limiting diffusion current was found to be directly pro- portional to the concWn-tration of the oxides studied.

For the preparation of the HBY 4 solution, chemically pure H3BO3 and an HF solution (whose concentration was deter- mined from its density) were used in the stoichiometric ratio, R 3BO3 being added (a small quantity at a time'. to the continuously stirred and ice-cooled BF solution. To the obtained HBF4 solution, also continuously cooled, nickel carbonate (a small quantity at a time) was a4ded and in this manmer it was possible to-obtain solutions Cardl/8 containing up to 180 g/litre nickel in the form of SOV/149-58-5-14/18 Electrode Processes in Blectro-deposition of Nickel from Fluoborate Electrolytes fluo'borate (density approx. 1-5), which could then be diluted to any required concentration. The characteristics of the experimental electrolytes (pH . 3 in all cases) are given in Table I which shows the nickel concentration (N . 1 to 4), the content (in g/litre) of fluorine, Fl, present in the form of BY303, the content of fluorine, F21 present in the form of BF,-, the total fluorine content F - 71 + F2 , the B content, the F/B and 7INi ratios, the NiC12*6H20 content, and the density at 20 OC. Nickel anodes and steel, copper or brass cathodes were used in the experiments, the results of which are reproduced graphically. The effect of the current density (A/dm2) on the cathode potential is illustrated in Figure 1, where graphs 1, 2,.3 and 4 correspond to the nickel concentrations of 1N, 2N, 3N and 4N, respectively. Figure 2 illustrates the current-donsity/cathode-potentiaI Card2/8 relationship for electrolytes with no excess of H 3 BO3 SOV/ 149-58-5-14/18 Electrode Processes in Electro-deposition of Nickel From Fluoborate Electrolytes i (graph 1) and with 5, 10 and 159/litre R BO -n excess 3 3 of the stoichiometric ratio (graphs 2,3 and 4). The results of the tests in which the current-density/cathcae- potential relationship was s8udied for 3N electrolytes containing no C1 ions at 20 C agd those containing 1~5, and 50 g/litre NiC12'6H20 at 50 C are reproduced in Figure 3 (graphs 1, 2, 3 and 4, respectively). The sa-me relationship for a 3N electrSlyte with no excess of A0 40 and 50 C is shown in Figure 4 H3BO3 at 20, ~ I - 1 to 4). A 3N electrolyte was also used for investigat---- the effect of the pH number which was varied between 1 5 by mean of HBF4 or sodium iodide additions. It was found that at pH = 5 , the electrolyte is unstable and contains black, insoluble particles (most likely Ni(OH) 2 wit basic salts) held in suspension. Pitting occurs and a dendritic deposit is obtained which at low current densities Card3/8 (1 to 5 A/dz2) becomes dark. At pH = 4 , low current SOV/149-58-5-14/18 Electrode Processes in Electro-deposition of Nickel From Kuoborate Electrolytes densities result in a dark deposit, while dendrites formed at high current densities. At pE = 1 or 2 intensive evolution of hydrogen takes place on the cath--.-Je surface, the evolved gas forming bubbles which adheTe t- the cathode and cause pitting.

Yield per unit current varies in all cases between 89.6 and 99 '/%, increasing with -Jncrea-~.-~ng current density and at high pi (3 to 4) values, and fai'Ling sharply at low current densities and at pH = 1 or 2 . In the next stage of the investigation the anodic procesc.es were studied. Four types of electrolytes were used containing (in &/litre): (A) 25 Ni(BF 4)21 68.5 Fl, 138.7 F2 and 34.4 B; (B) same as (A) plus 15 NiCl 2' 6E20; (C) 240 NiSO 4'7H20, 30 H3BO 3; (D) same as (C) plus 20 NaCl. Cathodes were made of electrolytic nickel or of non-passivating nickel containing C 0.2%, Si 0.2% anrl S G~00 (Ref 12). To reduce to minimum the difference between their Card4/8 true and the geometric surface areas, the cathodes were SOV/149-58-5-14/18 Electrode Processes in Electro-deposition of Nickel From Fluoborate Electrolytes olished first mechanically and then electrolyticall-'y to remove the plastically deformed layer). The results, f in the form of graphs showing the relationship between the anodic current density and the anode potential, are reproduced in Figure 5: graph (1 n -passivating nickel anode in electrol7te C; graph (B _- a0sn(l) but electrolyte D used; graph (3) - non-passivating nickel anode in electrolyte A; graph (4) - as (3) but in electrolyte B; graphs (5) and (6) - electrolytic nickel anode in electro- lytes C and D, respectively. When the ratio of the anode and cathode surface areas was S a/Sk = 2:1, the yield of the dissolved metal per unit current was high even in the absence of chlorides in the electrolyte but for F)s/Sk =1:1, a slightly lower yield was obtained. After the bath was operated for the equivalent of 800 A.hour per 1 1tre of electrolyte the concentration of the nickel- bearing salt in the solution was unchanged and only a slight rise in the pH number was observed. In their Card5/8 conclusions the authors state that: i) the main advantage SOV/149-58-5-14/18 Electrode Processes in Electro-deposition of Nickel From Fluoborate Electrolyte to be gained by using the fluoborate electrolyte instead of a sulphate solution for nickel plating is that the :rDcess can be intensi-fied, i.e. Ugher current densities can t;e employed without affecting the quality of the deposit and yet without reducing the yield per unit current. Tlie maximum permissible current density can be increased by increasing the Ni concentration in the electrolyte (up to 3N) and by using higher temperatuxesi a when the concentration of H 3BO3 in the electrolyte is increased, the cathode potential is reduced and so is the maximum permissible current density. In spite of this effect, which is probably due to partial dissociation of Ni(BF 30H)2 Ni(BF 4)2 to and to a decrease in the activity of the nickel ions in to maintain the H 3BO3 15 g/litre) above the stoichiometric ratio, Card6/8 stability of the electrolyte the electrolyte, it is recommended concentration slightly (approx. value corresponding to the since free H 3B03 improves the and makes it less reactive; SOV/149-58-5-14/18 Blectrode Processes in Blectro-deposition of Nickel from Fluoborate Blectrolyte iii) the effect of chlorides introduced in the electrolyte in the form of NiGl2.6H20 in amounts up to 15 g/litre is beneficial, since they reduce polarisation. However, at high (more than 30 g/litre) chlorides concentrations, the maxI-1- permissible current density is lower and the 0 quality of the deposit is adversely affected. At 50 C, the effect of the chlorine ions becomes insignificant, most likely owing to the reduced adsorption of these ions on the cathode surface and to sufficiently high activity of the sAode, particularly when made of non-passivating material. Owing to the latter factor, the fluoborate electrolytes are quite stable, so that in operation it is only necessary to replenish the fluoboric acid in order to maintain constant pE, since the anodic yield per unit current is slightly higher than the cathodic; (iv) the optimum value of the pH number of a fluoborate solution for nickel plating is between 3 and 3.5.

The solution of hydrofluoboric acid was prepared from hydrofluoric and boric acids by mixing the latter into the former in small doses accompanied by stirring and external cooling. Small doses of nxckel carbonate were added accompanied by cooling. Concentrates with a specific gravity Of 1.5 containing 180 g/litre of nickel can be obtained an fluoroborate of nickel. The fluoroborate of nickel has the formula Ni(BF4) .6H20 A method of analysis was used ' i sa, I.G. ("The Chemistry of Fluorine propose by Ry and its Anorganic Compounds" Monograph.

Nickel was determined by the alkaline solutlion Card 1/5 of di-methylglyoxime. 500 milli--litres of diluted SOV/122-59-5-22/32 Nickel Plating in Fluoroborate Electrolyte concentrate were used in each test with a nickel anode and a cathode of copper, iron or brass foil. The current efficiency was measured with a copper coulometer. The specimens were electro chemically degreased, pickled in nitric acid (copper, brass) or hydrochloric acid (iron), washed in water then in alcohol, dried, cooled and weighed, Befare j=iers2ng in the plating bath, the specimens were pickled in a 10% solution of sulphuric acid, washed in mains water and finally in distilled water. After plating, the specimens were washed in cold and hot water and in alcohol, dried, cooled and weighed. The curves of voltage against current density were plotted from measurements by the compensation method using a platinum disc cathode soldered into molybdenum vlass. Before taking the readings, the cathode was zovered by a 5 micron coat of copper from a sulphuric acid electrolyte.

Deposits of 25 microns are obtained without burns and dendrite formation at the corners. Further increase of concentration is not profitable. The concentration of boric acid has no effect on the current efficiency and the quality of the deposit. Solutions with a small excess of boric acid (10 g/litre) are more stable. The effect of chlorine ion concentration was studied by using electrolytes without chlorine ions and those with 15, 30 and 50 g/litre NiC12.6H20- Without chlorine ions, the quality of the deposit deteriorates., pitting increases, the current efficiency diminishes and the permissible current density drops. 15 9/litre is the beat concentration.

Sulphuric acid electrolytes were examined alongside the fluaroborate eleztrolytes. It was shown that fluoroborate electrolytes have a substantially greater buffer prcperty than sulphuric acid electrolytes with buffer admixtures.

The alloys, quenched in water after being main- tained 1-2 hours at a temperature of I I OOOC, had the micro- structure of a transformed A and molecular phase containing r%.* 10.50/. C. As an alloy's W content was increased, the micro- hardness of the molecular phase increased also, as a result of its enrichment with W. Quenching reduced the hardness of Ti-W alloys and increased their ~ . After being annealed at r-4 8000 they had a three-phase structure. a molecular phase and two solid solutions based on 0(-Ti and W. The microstructure of alloys which had been aged at 200-5000 for 10-24 hours retained Card l/?_ the acicular form it had acquired as a result of the quenching. 137-58-2-4253 Titanium- tungsten Alloys As the W content was increased. the formation temperature of the high- strength phase rose from 2000 (in the case of the Ti) to 400-5000 (in the case of the Ti/15%-W alloy). Gradual heating both intensified and raised the t.emp- erature of the dispersion -hardening process in the W-enriched alloys. Heat- ing to 6000 caused coagulation of the high-strength phase and a decline in hardness. At 650-7000, under a stress of 10-20 kg/mm2, the investigated al- loys exhibited a relatively low long-term strength, which increased, however,, concurrently with their W content. G.T. 1.

(Institute of Metallurgy, USSR Academy of Sciences) General Conditions for Forming Titanium and Its Alloys 124 Titanium and its alloys require special conditions for hot and cold forming. Cold deformation of TI (alpha phase), as In other metals with a hexagonal structure (Mg, Zn, etc.), is accompanied by marked twinning. Cold ductility of Ti is greater than that of''theBe other metals because of the greater number of possible slip and twinning planes. In a single cold-forming operation, Ti and its aommoner alloys can be deformed by not more than 30 percent. With fractional (or repeated) deformation the figure can be brought up to 80 percent. Cold working in a particular direction causes anisotropy to develop. The crystal anisotropy is weak, but the mechanical anisotropy rises sharply when car- Card 26/43 A UTHOR: -Panchenko, I.r.

TITLE: Screw Profiled Form Cutters (vintovyye fasonnyye PERIODICAL: Rezaniye metallov I instrument. Sbornik (14VTU, 1)4), Moscow, 14ashgiz, 1955, pp. 111-135 ABSTRACT: The author presents a mathematical analysis of the dewr,--e Of Drecision of a screw type thread form cutter and a method of calculating design data. It was establish,,~-i that the most important factors affecting the cutting precision are the taper ofC)o , the relief nd rake angles,and the angle of rofile diStortion~- . maxillium" error with,~'/, = 60 and is 1.4 mm. The longer tht- tapered part of the cutler=jeoc) and the shorter the C1 of the wider bas h e (f), the greater the error. Wit and-t = 30 mm, the error reaches I to 1.2 mm. The effect of other factors Is practically nil. On comparing the obtained data, the author concludes that screw profiled Card 1/1 form cutters are as accurate as disc form cutters. B.L.Ya. AIR JPOV.
