| Popis: | The effects of surface modification using an electrical discharge coating are investigated. The electrode used for the machining process is a Ti-type semi-sintered compact electrode. A thin and hard layer is formed on the machining surface. In this paper, the change in surface roughness during electrical discharge coating is described. The accretion layer surface became coarse after 10 min of machining. The peak height also increased. After 30 min of machining, the height of the accretion layer was lower than the original surface level, and the peak height decreased. Furthermore, the core roughness value increased. The surface roughness increased within several minutes from the start of electrical discharge coating using a Ti-type semi-sintered compact electrode. In this paper, we report on the temporal change of surface roughness during electrical discharge coating. |
