Wear of Retrieved UHMWPE Hip Liners
Yonsei Medical Journal, 2004 After the gamma-irradiation sterilization, the most widely used orthopaedic grade polymer bearing liner material for the total joint replacement, ultra-high molecular weight polyethylene (UHMWPE), degrades through the progressive in vivo oxidation. The oxidative degradation makes UHMWPE brittle and leads to reduction of its mechanical properties.

Tribology International, 2016 Abstract Friction and wear behavior of ultra-high molecular weight polyethylene (UHMWPE) sliding against TiAl6V4 alloy, against AISI316L austenitic stainless steel and against Al 2 O 3 ceramic under dry and lubricated conditions was investigated. Tests were conducted by using a reciprocating pin-on-flat tribometer with several applied normal loads ...
