Abstract

1404752 Coated sintered cemented carbide HOY CARBIDES Ltd 19 July 1972 [19 July 1971] 33837/71 Heading C7D A wear resistant article such as a cutting tool tip comprises a body of cobalt cemented tungsten carbide coated with an outer layer of cobalt. The cobalt layer 0.01 "thick may be applied by painting with a slurry of cobalt flake or powder in a volatile solvent and then sintering. Other coating methods such as electroless deposition, hydrogen precipitation from aqueous solution, sputtering, flame spraying or vapour phase deposition from a volatile compound. After coating the article is heated to effect diffusion.
