Abstract: Titanium-Niobium (Ti-Nb) based alloys are predominantly used as an implant material within the biomedical field due to their unique characteristics such as non-toxicity, better osseointegration, high resistance to corrosion, high strength-to-weight quantitative relation and biocompatibility. This paper proposes optimising the control parameters for the multi-response optimisation of Ti-6Al-7Nb biomedical alloy using Grey Relational Analysis combined with the Taguchi approach. Wear rate (WR), coefficient of friction (COF), and frictional force were the response characteristics studied (FF). The Taguchi methodology is used in conjunction with the grey interpersonal evaluation as a performance index to determine the best set of control parameters. Applied Load, Rotational Speed, and Time were the control parameters evaluated. Experiments are designed using L9 Taguchi’s orthogonal array and conducted on a pin-on-disc setup by ASTM G99. The experimental outcomes indicate that the applied load has the most significant impact on the various wear characteristics of the Ti-6Al-7Nb biomedical alloy. This approach has been successfully used to recover the wear response of Ti-6Al-7Nb biomedical alloy through a rummage sale.
