Diffference between Nickel Strike plate and Typical Nickel plating(2007)
I am trying to explain the difference between a Nickel Strike plating and a typical Nickel plating.Mark Kane

Nickel strike: Higher content of chloride, is going to be used for direct plating of steel if cyanide copper is not requested. Content usually: Nickel chloride, HCl
Watt's Nickel: Is going to be used for decorative reasons. Content: Nickel sulphate (metal delivering), Nickel chloride (anode dissolving agent), Boric acid (ph-buffer agent), wetting agents and primary/secondary brightener systems depends on application.

A "strike" is a low efficiency solution that makes more hydrogen gas than it deposits metal. The purpose is to "activate" (I hate that word) or remove the oxide from the substrate and lay down a thin film of very active ready-to-plate nickel. The hydrogen ion helps reduce the tenacious oxides of stainless steel or old nickel electroplate from the surface. Secondly, the strike acts as a "sewer". The strike covers the substrate iron, copper,. brass, zinc, zincate, etc so that when you get to the "efficient" plating solution you do not leave contaminants of those (now covered up) other metals.
