Abstract
An improved direct current chrome plating process which results in increased corrosion resistance as compared to conventional processes. Particularly, in comparison with conventional processes, an improved process as broadly contemplated herein can preferably include an additional processing step involving the application of a distinct chemical solution. This additional step, consequently, will lead to a chrome plated product having variant layers of chrome plating rather than the single layer as produced conventionally.
Claims39
A method of chrome-plating a substrate, said method comprising the steps of:
- providing a substrate;
- applying a first chrome layer onto the substrate, the first chrome layer being crack-free;
- applying a second chrome layer onto the first chrome layer, the second chrome layer comprising micro cracks;
- said step of applying a first chrome layer comprising applying a first chrome plating solution which comprises catalyst in a concentration of between about 0 percent and about 20 percent vs. active ingredients.
