Method of electrodepositing onto stainless steel

Abstract

Abstract A process by which a metal may be plated on a stainless steel metal substrate whereby the final electro-plated composite possesses greatly improved adherence. Said process involves the electrodeposition of a chromium strike layer on the stainless steel base metal which is then followed by a nickel strike layer prior to plating of said metal. The chromium strike layer may be deposited from any standard chromium electrodeposition plating baths. The nickel strike layer may be deposited from a ''''Woods strike'''' nickel electroplating bath which can be either bromide or chloride. The bromide type is preferred and the composition and operating conditions of said bath comprise: NiBR2 100-800 g./1. HBr 0.1-20% by weight Current Density 5-200 a.s.f. Bath Temperature 60-115* F.
