Tribological Properties of Surface Modified Layer of Titanium using EDM Process

In this paper, we describe the tribological properties of the carbonization layer of titanium using EDM process. Modified layer under optimum conditions had a high carbon content and had an amorphous carbon area at the crater circumference. By using this method, a TiC layer with excellent tribological properties, low friction coefficient, minimal fluctuation and wear of mating material ball was obtained. This effect was suggested to influence amorphous carbon area of the extremely surface. The EDM process proved to be effective for the efficient surface modification of titanium.
