Method of coating titanium and its alloys

摘要

A process for improving the wear resistance of, and reducing the frictional forces between, bodies made of titanium or its alloys, in which surfaces liable to wear are coated with a layer of a metal such as tin of aluminium which is then bombarded with ions of a light species such as nitrogen, carbon, boron, or neon so as to cause the metal to migrate into the titanium.
