Composite material consisting of a metal matrix and talc

Résumé

The invention concerns a lubricating metal coating, and a method for making same. The material constituting the coating is a composite material comprising a metal matrix wherein are distributed sheet talc particles, the metal matrix consisting of a metal selected among Fe, Co, Ni, Mn, Cr, Cu, W, Mo, Zn, Au, Ag, Pb, Sn or of an alloy of said metals, or of a metal-metalloid alloy. The coating is obtained by a method which consists in carrying out an electrodeposit using a solution of precursors of the metal matrix of the coating containing additionally suspended talc particles surface-modified by irreversible adsorption of a cellulose-derived compound by substituting all or part of the hydroxyl groups.
