Abstract

Periodic introduction of different material combinations such as metal-metal, metal-polymer, ceramic-polymer and ceramic-ceramic as the articulating surfaces in artificial total hip arthroplasty exhibited their own merits and demerits. Since the wear between the mating parts of the prostheses ultimately determines the life of the prostheses, tribological performance of the three materials combination used in total hip replacement (THR) was studied with a pin-on-disc (POD) machine and the results were compared. It was observed that in different material couples, a power law form of relationship existed between wear height and load though it changed with severity of abrasion. Alumina-alumina material combination exhibited very low wear with occasional grain pull-out and the generated data clearly established the superiority of the ceramic based material-couples. In SS 316L-UHMWPE, abrasion dominated wear was observed while in Al2O3-UHMWPE, abrasive ploughing was followed by an adhesive form of junction making and breaking which in turn resulted in the formation of transfer film.
