Tests on nickel anodes

Nickel anodes, such as are used for replenishing the solution in nickel plating, have formed the subject of a recent investigation at the Bureau of Standards. The purpose was to determine the relative behavior of different forms of nickel, such as electrolytic, rolled, and cast nickel, in the solutions used for electroplating. A study was also made of the effect of impurities, both accidental and purposely added.
