Beschreibung
Zusammenfassung:	There is provided a method and composition for applying a wear resistant composite coating onto a metal surface of an electrical component. The method comprises contacting the metal surface with an electrolytic plating composition comprising (a) a source of tin ions and (b) non-metallic particles, and applying an external source of electrons to the electrolytic plating composition to thereby electrolytically deposit the composite coating onto the metal surface, wherein the composite coating comprises tin metal and the non-metallic particles.
