ELECTROPLATING OF RHODIUM-RUTHENIUM ALLOYS

摘要

RHODIUM-RUTHENIUM ALLOYSABSTRACT OF THE DISCLOSUREDisclosed is an electroplating bath suitable fordepositing a rhodium-ruthenium alloy containing at least 90weight % rhodium. Rhodium and ruthenium axe present in theplating bath in the form of soluble platable compounds in apreferred weight ratio of at least about 10:1. The depositsobtained by this bath exhibit improved brightness over comparablebaths even without the addition of lead, and also exhibitreduced stress as compared to deposits obtained from rhodium-platinum baths.
