ジャーナル フリーThe experiment was performed in order to investigate the mechanism of generation of luster on zinc diecast by using various compounds including anionic, nonionic, or cationic surfactant.
As a result, it was found that the degree of luster varies depending on the kind of surfactants used. The compound such as sodium stearate, toilet soap, polyethylene glycol monolaurate, polyethylene glycol lauryl ether, sodium salt of sulfonated lauryl alcohol, polyethylene glycol alkyl aryl ether, polyoxyethylene oleyl ether, or polyoxyethylene sorbitan monolaurate gave favorable result. However, the luster of the test pieces was poor when sodium lauric, soyabean-oil soap, or cation surfactants was used.抄録全体を表示PDF形式でダウンロード (427K) -

ジャーナル フリーMill agents for Al-frit are added to control the flowing, suspention and viscosity of slip, and protect its surface before fusion has taken place, and also alleviate the reaction between slip and metal.
In the present experiment, to borosilicate system frit (SL 10), added were the mill agent, such as bentonite, sodium metasilicate, ammonium molybdate, sodium aluminate, ammonium carbonate, boric anbydride+sodium metasilicate, etc.
In each case the test was made as to the extent of flowing, suspention and viscosity of slip.
The result may be summarized as follows:
(1) The limit of mill addition of sodium aluminate and ammonium carbonate for effective prevention of slip from flowing was 0.3-0.4%.
Sodium metasilicate, when added up to 0.5%, showed good effect for flowing-prevention, suspention and viscosity of slip, but the finish of enamel surface was not good.
0.5% ammonium molybdate pretty well promoted the adhesion to metal. Up to 0.5% bentonite content had good effect in suspention and viscosity of slip.
(2) With boric anhydride and sodium metasilicate (1:1) up to 0.7%, a very good result was obtained in flowing prevention, viscosity and suspention of slip.
With 0.5% bentonite added to the boric anhydride and sodium metasilicate (1:1) bath, the result was much better than the previous one.抄録全体を表示PDF形式でダウンロード (1222K) -

ジャーナル フリーTo study the mechanism of electrodeposition of aluminum from the hydride bath, the present experiment was carried out, and the result was as follows:
1. The most suitable composition for obtaining the best deposition was as follows.
AlCl3 2-3M/l LiH 0.5-1.0M/l in ether
DK=5-40mA/cm2 at room temperature
2. The conductivity of the ether solution of AlCl3, LiH, LiAlH4, LiCl, NaH or their mixture was measured, and it was found that the conductivity of the solution containing AlCl3 was greater than others, and NaH decreased the conductivity of AlCl3 solution, from which it might be concluded that AlCl3+LiH, LiCl or LiAlH4 would produce complex ions in ether.
3. The electrodeposition overpotential was measured by the commutator method, and it was found that a Tafel equation held well in the bath from which electrodeposition of aluminum could be obtained, and that the rate-determinant was three electron reactions.
From the above, it was supposed that for obtaining the electrodeposition of aluminum, a complex ion containing Al3+ of relatively small stability constant must exist in the bath, and Al3+ produced from this complexion would be discharged at the cathode.抄録全体を表示PDF形式でダウンロード (533K) -
