The developments of Al and V free, biocompatible Ti-alloy have been the subject of researcher in the orthopedic joints replacement domain. The current article addresses the methodology chosen for Ti-alloy design, machinability, and low-cost surface texturing process for a high degree of biocompatibility. It is evident that an astonishing increase in biocompatibility can be achieved by synchronizing electro-discharge spark energy within Ti alloy and tool material coupled with the selection of dielectric medium for surface modification. The finding of this research may benefit a wide range of researchers to design sustainable implants. The positive polarity tool electrode at 10 A is the most desirable process parameter developing the bioactive surface.
