Surface Modification of Titanium using EDM Process

Abstract

Surface modification of titanium using EDM process was studied. To form a new titanium carbide (TiC) layer on the machined surface, finishing EDM process was examined. TiC layer with crack less surface was obtained in the relatively short discharge duration with low discharge current range under the electrode negative polarity.And the various effective improvements in machined surface such as hardness, tribological properties and corrosion resistance were obtained respectively.
