Abstract
Stress in electrodeposition was measured by means of the same equipment as described in the first report, and under various electrolytic conditions using Watt's type bath, plain bath, all chrolide bath, and sulphamate bath.
The result is as follows:
(1) Effects of temperature, current density, pH, Ni++, and Cl- on the stress were almost the same as reported by Brenner and others. The value of stress in Watt's type was the lowest when H3BO3 was about 30g/l.
(2) MgSO4⋅7H2O of 0-200g/l or Cu++ and Zn++ of 0-0.05g/l had almost nothing to do with the stress.
(3) Some organic impurities increase the stress.
(4) When Watt's type bath or all chloride bath was air-agitated, the stress was increased about 7×103 p. s. i.
