Process for the continuous electrolytic plating of metal wire, strips, chains, and gauze strips with metals

摘要

A process of electro-plating elongate articles of passive metal with a thin, homogeneous coating of a noble metal. The article is passed through an electrolyte bath comprising a salt melt of alkali metals or alkaline earth metals containing a cyano radical. The articles are guided through the bath by guides of a material selected from oxides of aluminum, silicon, yttrium, or zirconium; nitrides of silicon, borium, or titanium; or carbides of silicon or titanium. The entire process is carried out in an inert atmosphere.
