Title: Method for concomitant particulate diamond deposition in electroless plating, and the product thereof

Abstract: This invention is a method for depositing on an article a coating containing at least one member of the group metals and metal alloys plus particulate dispersed diamond comprising contacting the surface of the article with a stable electroless plating bath consisting essentially of an aqueous solution of soluble constituents of the group, electroless reducing agent therefor, a suspension of diamond particles therein and a stabilizer, and maintaining the diamond particles in suspension throughout the bath during the coating of the article for a time sufficient to produce a preselected depth of coating on the article, and the coated article per se.
