クロムメッキの耐摩耗性 (第1報)石田 武男1963 年 14 巻 1 号 p. 21-24

ジャーナル フリーStudy on the wear resistance of the electrodeposited Cr was carried out using Nishihara's wear testing machine.
When Cr deposit was combined with Cr deposit, the surfaces were without lubricant, scorched extremely. Employing water or oil as lubricant, however, the wear of the test pieces was found to be small, and the surface was smooth.
Wear resistances of the Cr deposits plated under various conditions or treated at various temperatures were measured to find out the relation between the wear resistance and the hardness of the Cr plate. It was found that the Cr deposit of heterogeneous structure had greater wear resistance irrespective to its hardness.抄録全体を表示PDF形式でダウンロード (1153K) -

ジャーナル フリーThe corrosion rates of various metallic and nonmetallic materials dipped in the condensed phosphoric acid (CPA) which contains 72 or 85% of P2O5 were observed in the range of temperature from 50°C to 300°C by the methods described in the previous paper.
The results obtained are as follows.
1) The corrosion rate of Illium R (Ni-base alloy) is larger than those of Hastelloy B and C.
2) The corrosion rate of Hastelloy B polarized anodically is very small but larger compared with that of Ta.
3) The unticorrosivity of glass can be improved by increasing SiO2-B2O3 and decreasing alkaline in its components.
4) The impervious graphite and polyfluoroethylene resin are sufficiently unticorrose below their allowable temperature.
According to the results in the present and previous papers, Ta is the most unticorrosive material dipped in CPA below the temperature of 200°.抄録全体を表示PDF形式でダウンロード (849K) -
