Abstract : The Cobalt (Co)–Chromium (Cr)–Molybdenum (Mo) (Co–Cr–Mo) alloy and Ultra High Molecular Polyethylene are the important materials used in the biomedical applications and Bio-inerts lime hip implants, ophthalmological implants and dental implants are increasing day by day due to their unique wear resistance characteristics. This paper presents the tribological behavior of Co–Cr–Mo alloy on Ultra high molecular polyethylene with and without third body particles. Polymethylmethacrylate (PMMA) bone cement in 5 g/L concentration is used as third body particles. In the present investigation, pin on plate wear test is carried out using ducom linear reciprocating tribometer, to evaluate average wear rate, Coefficient of Friction (COF), and frictional force between Co–Cr–Mo alloy and Ultra High Molecular Polyethylene with and without third body particles under load condition of 20 N, stroke of 6 mm, and frequency of 5 Hz. The test is carried out for one lakh cycles and sliding distance of 1200 m. The results indicate increase in wear rate, COF, and frictional force with third body particles compared to the ones without third body particles.
