ABSTRACT:
A process is described for the reception of composite electroless plating onto a non-catalytic metal or non-catalytic alloy, non-catalytic to composite electroless plating. The process comprises contacting the non-catalytic substrate with a promoter composition containing ions selected from the group of nickel, cobalt, iron, and mixtures thereof and a suitable reducing agent, and thereafter contacting the treated surface with a composite electroless plating bath comprising particulate matter to deposit a metallic layer with finely divided particulate matter dispersed throughout.
