Abstract
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.
Claims10
A process for improving the wear resistance of titanium and its alloys comprising the operations of coating a surface of a workpiece made of titanium or an alloy of titanium and which is likely to be subject to wear with a layer of a metal selected from the group consisting of aluminium, copper, iron, tin, nickel, platinum, zinc and zirconium, and then subjecting the coated surface to bombardment with ions of a light species the mass of which is insufficient to cause a harmful degree of sputtering of the surface during implantation, so as to cause the metal to migrate into the workpiece.
