Electrical discharge machining- a futuristic technique for surface engineering of biomedical alloys: a concise review

Electrical discharge machining(EDM) has proven effective in the processing of tough and complicated structural materials that are often challenging to manufacture or alter using traditional machining techniques. EDM represents a promising technique for the surface engineering of biomedical devices. In this article, electrical discharge machining is discussed for its high precision in surface modification as well as surface properties. According to previous studies on this non-traditional machining technique, optimizing critical EDM process variables such as pulse duration, voltage, current, polarity, dielectric fluid, and electrodes can yield adequate surface integrity and bioactive coating on alloys. As a result, the EDM process could be prospectively employed to examine issues including bioimplant manufacture and precision modeling.
