Bodies made of titanium or its alloys, having surfaces liable to wear, have their wear resistance improved by coating such surfaces with a layer of a metal such as tin or aluminum which has been 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 or titanium alloy. The modified surface has improved wear resistance and reduced coefficient of friction.

Titanium and its alloys

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.
