ジャーナル フリーThe chemical deposition of nickel is based on a catalytic reduction of nickel ions in the presence of hypophosphite ions. The rate of deposition and hydrogen evolution was measured and the reaction mechanism was discussed. The alkaline bath favors the reaction, however, the primary deposition of a catalytic metal is required to initiate the reaction.
The deposition potential was found almost independent of the base metal and temperature and becomes linearly less noble with an increase in alkalinity of the bath.
The hardness of the plating has no remarkable change in the acid or neutral bath, whereas it increases in the alkaline side. The heat treatment at 400°C gave the highest hardness.抄録全体を表示PDF形式でダウンロード (1417K) -

ジャーナル フリーAluminum and its alloys (99.98, 99.9, 99.3, 99.2, 3S, 52S, 17S, Alcoa 355, Silumin and Hydronalium) were anodized in the aqueous solution of sulfamic acid (20-50°C, 5-20wt%) with d. c., 1A/dm2. Relations between bath voltage (V) and anodizing time (T) were examined, and the formation of the porous coating on the anode was confirmed as shown in Fig. 2-17.
At higher temperatures and concentrations, steady forms in V-T were obtained and uniform coatings were formed on the anodes. However, at lower temperatures and concentrations, fluctuated forms in V-T were obtained, and local corrosion of the anode could be observed.
It may be considered that the weak solvent action of the electrolyte on the coating produces the compact coating at first, and then locally attacks the coating at the weak points. It is also presumable that the successive and concentrated current through these points results in local corrosion as illustrated in Fig. 18-27 and Photo 1-5.抄録全体を表示PDF形式でダウンロード (1525K) -

ジャーナル フリーNickel-electroforming mold made of non-conductive materials should be provided with some conductive film which has usually only a very low degree of adhesion.
Since electroformed nickel has generally a large internal stress, it is natural that the electroformed-nickel shell, electrodeposited directly on the conductive film would be deformed by its own internal stress resulting in bad adhesion.
The internal stress of electrodeposited nickel may be affected not only by the electroforming bath composition and plating condition, but by the surface roughness of the mold.
The authers studied the range of the internal stress permissible for obtaining nickel shell electro-formed on the conductive film without deformation, and observed the effect of the surface roughness on the internal stress of electroformed nickel.抄録全体を表示PDF形式でダウンロード (2538K) -

ジャーナル フリーThe phosphate system enamel containing no lead was produced and fund to be suitable to the plugging material of fluorence substance of the Electroluminescent.
Aluminum plates were pretreated by the chemical and anodic oxidation method, to which the phosphate frit without lead was applied.
The adhension of enameled plates were investigated by bending and thermal shock test, and the corrosion was also tested comparing lead system enamel with phosphate system enamel without lead. The results:
1) In the bending and thermal shock test, aluminum and alloy plates of chemical treatment showed no good adhension for frit. Aluminum and alloy plates of anodic oxidation treatment showed the same good adhension as borosilicate and lead frit. In the thermal shock test, anodic oxidation treatment of alloy plates with sodium perborate, lithium borate, sodium phosphate and sodium perborate-sodium phosphate-potassium phosphate showed especially good adhension.
2) In the corrosion test, the phosphate enamel without lead showed superior resistant to lead system enamel against inorganic acid.抄録全体を表示PDF形式でダウンロード (910K) -
