Abstract
A titanium-containing metallic material having a high heat-resistant and abrasion resistant surface is produced by (A) cleaning a titanium-containing metallic material, (B) first plating the cleaned surface of the metallic material with Cu or Ni by a strike or flash plating method, (C) second plating the first plated surface of the Ti-containing material with Ni, Ni-P alloy or a composite material comprising a Ni-P alloy matrix and fine ceramic particles dispersed in the matrix by an electroplating method, (D) non-oxidatively heat treating the second plated Ti-containing material at 450.degree. C. or more for one hour or more, (E) surface activating the second plated surface of the Ti-containing material, (F) coating the activated surface of the Ti-containing material with a heat and abrasion resistant coating layer comprising a matrix consisting of a Ni-P alloy or cobalt and fine ceramic particles dispersed in the matrix, and optionally, (G) surface-roughening the heat and abrasion-resistant coating layer surface of the Ti-containing material to a R.sub.Z of 1.0 to 10.0 .mu.m, and (H) coating the roughened surface of the Ti-containing material with a solid lubricant coating layer …
