Abstract
Abstract A composite of organic resin, preferably an elastomer, and ceramic useful for wear-resistant linings for ball mills, conveyors or chutes for abrasive materials, truck bed linings and the like comprising ceramic pieces with metallized surfaces and with the organic resin bonded to the metallized surfaces of the ceramic, the metallized surfaces being applied to the ceramic by contacting the ceramic with metal, preferably titanium or zirconium with sufficient force and relative motion to cause the metal to be bonded to the ceramic.
