| Summary: | Surface texturing is a distinct identical feature of discrete dimples or grooves on a surface. In a biomedical application such as hip implant, it has been proven that these dimples can enhance the tribological properties of journal bearings. Realizing the advantages offered by Electrical Discharge Machining (EDM), it was utilized in this research to machine the dimples for the Metal-on-Metal hip implant application. In this research, three sets of inclined angles of 50°, 70°, and 90 were machined on the S24C mild steel material using EDM with pulse currents of 1A, 2A, and 3A. This research focuses on micro-crack formation along the edge of the surface of the dimple after EDM machining, which is critical in a contact sliding bearing. |
