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.
