Development of a new surface modifying technique using ELID grinding with high temperture treatment

Abstract

In order to apply an ELID (Electrolytic In–process Dressing) grinding as a finishing method for precise metal mold, we performed a detailed analysis of the ELID ground surface. The analysis of the ground surface was performed by an X–ray Photoelectron Spectroscopy (XPS) and then the roughness of ground surfaces were measured by a contact type roughness meter. Results showed that the ELID ground surface after oxidation treatment created a thicker oxide layer with different structure and achieved the high quality surface compared with the polished surface.
