Precious metal plating involves the deposition of a thin layer of precious metals such as gold, silver, platinum, rhodium, palladium or their alloys on a surface. This galvanization process is frequently used in small series of jewelry, all the more because of the expensive electrolyte. Other examples are dental applications, but also various continuous electroplating processes in the production of semiconductors, connectors and other parts for the electronics industry.
Precious metal plating processes may be currentless in some cases, but most contemporary applications and advanced baths require the use of electrical current. Depending on the exact application, soluble anodes, e.g. silver or gold plates in solution or inert platinized MEPLA – titanium mesh anodes, can be used in these so-called electrodeposition processes.
Within the industry, mainly small process baths and therefore small anodes are used. ME-Metals & Technologies has suitable mesh anodes in stock, provided with a MEPLA platinum-plated coating of 1.5 and 2.5 mµ Pt.
