Abstract : The patent describes a metallic bond formed between a quartz surface and a stainless steel surface by an electroplating method. The method includes plating a thin layer of a low stress electrically conductive metal such as nickel, gold or copper, onto a composite chromium-copper (Cr-Cu) film which is strongly adherent to quartz. The quartz coated surface is placed in physical and electrical contact with the stainless steel surface, and the low stress electrically conductive metal plated from a suitable plating solution onto both the quartz coated surface and the stainless steel surface.
