A PROCESS FOR COPPER PLATING OF METALS AND THEIR ALLOYS SUCH AS STAINLESS STEEL TANTALUM AND TITANIUM

摘要

A process for the copper plating of metals and their alloys such as stainless steel, tantalum and titanium comprising the cleaning, roughening and etching of the job prior to electroplating thereof, characteried by activating the surface of the job by immersion in an activating bath containing copper sulphate, fluoride ions and a known wetting agent such as herein described: and electroplating the job in a known manner, thereafter, in a bath containing copper sulphate, fluoride ions and sulphuric acid.
