Abstract: The method of electrical discharge coating with TiC ceramic layer in ordinary electrical discharge machining(EDM) tool was studied systematically. Through the metallography, X-ray diffraction, sector scanning research and wear test, the characteristics of the ceramic layer were studied, and the effect of the discharge parameters on the quality and the thickness of the coating was also discussed. The results show that this method is a very potential surface modification method. Comparing with other surface peeling technologies, that coating layer thickness is more than 20μm, the hardness is increased by 2-3 times, the wearing resistance is increased by 5 times and the product life is increased by 3-5 times.
