  • PROCESSES FOR TEXTURING A SURFACE PRIOR TO ELECTROLESS PLATING
    Publication number: 20090302005
    Abstract: Process for roughening a surface of a base metal substrate includes contacting the surface with an aqueous solution comprising oxalic acid, sulfuric acid, and hydrogen peroxide at a temperature and for a period of time effective to roughen the surface to an average roughness greater than 60 Ra, removing a modest amount of base material, and generating no narrow and deep crevices at all. The surface is roughened prior to application of an electroless coating onto the substrate.
