Abstract

A new method double-glow discharged plasma non-hydrogen carburizing on the surface of titanium alloy (Ti-6Al-4V) is introduced Using this method, there is no hydrogen brittleness and the wear resistance property of titanium alloy is greatly improved. The friction coefficient of the carburized surface is much more decreased. The pressure in the chamber for carburizing is 5×10^-3Pa, and the discharged gas is of high purity argon gas (99.999%). The carburized layer is composed of TiC. The thickness of the carburized layer is more than 200 μm. The microhardness of the carburized surface is 7000 MPa. Phases structure and microstructure of the carburized layer were determined by using XRD and SEM.
