Abstract
PURPOSE: To carry out electroless Ni plating with high adhesion by striking a high Ni.Cr alloy with Ni and activating the struck surface.
CONSTITUTION: A high Ni.Cr alloy is pretreated by degreasing and pickling and struck with Ni. The struck Ni surface is then activated by acid treatment with a strong acid such as a soln. of nitric acid and hydrofluoric acid, and immediately after washing, electroless Ni plating is carried out. In place of the acid treatment activation, the struck alloy may be subjected to electrolytic elution as an anode in an Ni plating bath at relatively low current density to obtain similar effect.
