Procedure for Nickel Strike (Wood’s Nickel)
(activation of stainless steel, nickel and nickel alloys)
Plating on stainless steel, nickel and nickel alloys requires that the basis metal be given an activating treatment before electroplating to assure adhesion of coatings. The recommended treatment is to clean then to strike the parts in a Wood’s nickel strike solution. The work should be
cleaned in a manner consistent with the base
material, rinsed, made
cathodic, with nickel striking taking place at 15 to 20 asf for one minute,
or until a continuous nickel plate is obtained. The work is then rinsed
and plated per requested specification.
