TRIBOLOGICAL WEAR OF POLYTHENE UHMWPE APPLIED IN BIOTRIBOLOGICAL SYSTEMS
Journal Title: Tribologia - Year 2012, Vol 241, Issue 1
Abstract
The paper presents the results of the tribological tests for materials used in elements of hip and knee endoprostheses. The tests were conducted for a CoCrMo alloy and an ultra-high molecular weight polyethylene (UHMWPE). The topography and the texture analysis were determined by applying scanning electron microscopy and profilometer. The tribological characteristics were obtained with a T-17 tester operating in the pin-on- -plate configuration under lubricated friction conditions. The friction pair consisted of a cobalt-based alloy plate and an ultra-high molecular weight polyethylene pin. The model lubricant used in the tests was Ringer’s solution. The results indicated that the wear resistance of the endoprosthesis elements was mainly dependent on the material used for the working surfaces in the friction joint.
