Description

Polymer debris from the sliding wear of a rotating steel wheel on flat polyethylene was traced using the radioisotope indium-111 to identify wear debris pathways. The radioisotope was ion-implanted just below the surface of ultra-high molecular weight polyethylene samples at a mean implantation depth of 144 nm. The implantation fluence was 4 × 1012 ions/cm2 or less. Several samples were actuated by the rotating wheel with two different normal loads and varying actuation regimes in a water...[Show more]
