ABSTRACT:
A method of preparing a surface of a silicon carbide article for joining by metal brazing to metal by micro-roughening that surface of the silicon carbide which is to be brazed, applying catalyst consisting essentially of aqueous PdCl.sub.2 directly to the micro-roughened surface, in the absence of pretreatment of said surface with stannous chloride, and electrolessly depositing a thin layer of metal selected from the group consisting of Ni, Cr, Au, Ag and Cu on said catalyst-treated surface.
