Abstract
A process for tungsten alloy plating wherein a tungsten replenisher concentrate of tungsten ions pre-complexed with a hydroxy carboxylic acid is used for maintenance additions to the bath. A preferred additive includes from about 100 to about 120 g/l of tungsten ions complexed with from about 120 to about 220 g/l of citric acid. The process provides consistent cathode efficiency and produces ductile deposits of tungsten alloy electroplate.
