ABSTRACT

In engineering applications when materials start sliding against each other the problem of friction and wear appears. In the case of polymers the friction between them can be attributed to two main mechanisms: deformation and adhesion. One of the important application fields for polymers is the medical engineering. In this field, the UHMWPE polymer is one of the important candidant polymer material. In this investigation, the friction and wear performance of GUR 1020 medical grade UHMWPE polymer under dry sliding conditions is evaluated. The sliding experiments were carried out on a pin-on-AISI stainless steel disc arrangement. Wear tests were carried out under room temperature, 50, 100and 150N load values and at 0.50, 1.0 and 2.0m/s sliding speed conditions. The results show that the coefficient of friction for GUR 1020 medical grade UHMWPE polymer is significantly influenced by applied load, sliding speed values. Furthermore, the coefficient of friction and specific wear rate increases with the increase in applied load and sliding speed values. The specific wear rate values for GUR 1020 medical grade UHMWPE polymer under dry condition is at the order of 8x10^-14 m²/N. The friction coefficients vary between 0.12 and 0.20. Finally, the wear mechanism includes abrasive and adhesive processes.
