Abstract

Surfaces of Cu or Cu alloy articles are first polished and coated with a protective film by immersion in a bath containing HCl, H2O2, and glycerine or EDTA acid, then rapidly moved to a second bath comprising H2O2 which oxidizes the film to a stable state. The film may be dissolved in a third bath of HNO3 prior to metal coating by electrodeposition or soldering. The first bath may contain nitric and orthophosphoric acids and stabilisers for H2O2 e.g. tartaric and acetic acids and glycerine with NaCl.
