Abstract
A method of catalytically activating refractory metal surfaces for the subsequent electroless plating of another metal thereon is disclosed, in which the refractory surface is treated while heated in a carburizing atmosphere under conditions which cause the formation of refractory metal carbides on the refractory surface.
Claims8
A method of catalytically activating a refractory metal surface for the subsequent electroless plating of metal thereon;
- said method comprising treating the surface while heated in a carburizing atmosphere under conditions which cause carbon to react with refractory metal atoms at the surface, said carburizing treatment followed by the electroless plating of a metal selected from the group consisting of nickel, cobalt, and gold onto the refractory surface.
