碩士 === 國立雲林科技大學 === 機械工程系碩士班 === 90 === In this study, it adopted the hollow spindle connected with disk electrode and the Titanium was to be the material of disk electric. Then, added the mixture that consisted of the carbon powder and dielectric into the spin disk electrode. According to the centrifugal force produced by the turning disk electrode, it would fling out the mixture. The SKD-61 and WC were to be the substrate. They proceeded the coating of surface and melted the electrode and substrate during the EDM process. After melting the carbon powder between the electrode and substrate, it and the carbon iron that was separated from the mixture would be blended to the coating layer. In order to know the effects of TiC layer according to the parameter and get the better parameter, this study used Taguchi method to do the research and did the analysis after the experiment. The spindle speed, peak current, pulse width and the carbon powder concentration were to be the parameters of the experiment. To probe the effect that the EDC TiC layer is to the change the parameter, this study focused the result including to the wear resistance of electrode, the surface roughness, the hardness, component and the thickness of the layer to analyze and discuss. The result was found that the more carbon powder concentration the higher hardness was. Moreover, if the releasing electricity last longer, it would get the maximum width of the layer. It produced the excellent surface when the current decreased.
