抄録

Co-Cr alloy used as a biomaterial is required to possess excellent resistance to corrosion, wear, and corrosion fatigue. In addition, it needs to have a mirror-like surface finish for improved chemical stability. In the present work, we performed Electrolytic In-Process Dressing (ELID) grinding of Co-Cr alloy, and evaluated the processing characteristics and the resulting surface properties. Final finishing using a #8000 wheel produced an extremely smooth ground surface with a roughness Ra of 0.005 μm. In addition, samples ground using ELID demonstrated superior surface hardness compared to those of the as-polished samples. These advantages can be attributed to the diffusion of oxygen produced during ELID grinding.
