Platinum and platinum alloy electroplating baths and processes

摘要

A procedure is described for electroplating platinum and platinum alloys. This procedure permits rapid electroplating of platinum and yields platinum films with excellent properties. The electroplating bath comprises a unique platinum complexing agent, namely an organic polyamine compound. The procedure is also useful for electroplating a variety of platinum alloys. In addition, the bath is highly stable and does not adversely affect the base material being plated.
