Electric discharge machining of Ti-6Al-4V alloy for biomedical use
Original language description
Ti-6Al-4V alloy was subjected to electric discharge machining (EDM) as a surface treatment process. Several experimental investigations have been undertaken in order to assess whether EDM process is a viable surface treatment technique for application inorthopaedics. The surface roughness, chemical alterations of surface and osteointegration in vitro have been studied. EDM with relatively high peak currents induced sufficient surface roughness and created carbon enriched surface layer for improved osteointegration. Tensile properties are not substantially varied by EDM, however EDM has detrimental effect on fatigue endurance. Poor fatigue performance of material after EDM process irrespective of its original microstructure can be attributed to surfacemicrocracks, brittle oxidized surface recast layer, internal tensile stresses and notch sensitivity of titanium alloys. These detrimental effects can be partly avoided by subsequent heat treatments. Microstructural changes of surface and
