Abstract

1,258,405. Modifying metallic surfaces. ROLLS-ROYCE Ltd. Nov. 21, 1969 [Nov. 23, 1968; Feb. 8, 1969], Nos.55662/68 and 6963/69. Heading C7U. A metal, e.g. steel or Ni-base alloy, surface is coated by applying a composition comprising a phosphate glue, Al powder, which is at least 50% of the composition, and a buffering agent e.g. chromic acid or potassium dichromate and then heating at 500 to 1000‹C, for ¢ to 8 hours in air or an inert gas. The phosphate glue may comprise phospheric acid, aluminium phosphate and water.
