The wear behaviour of UHMWPE and ion implanted UHMWPE against differing counterfaces

A study has been made of the tribological behaviour of ultra high molecular weight polyethylene (UHMWPE) and ion implanted UHMWPE during water lubricated reciprocating sliding against differing stainless steel and Yttria Partially Stabilised Zirconia (YPSZ) counterfaces. A new laboratory test apparatus was designed, built and commissioned to facilitate this research. The new apparatus is capable of simulating the reciprocating wear of a sliding couple under diverse conditions of pressure, sliding speed and lubricant environment, as well as allowing the measurement of frictional forces 'encountered between the two surfaces in sliding contact. Variation in stainless steel counterface surface roughness resulted in three different types of wear behaviour.
