Evaluation of Two Total Hip Bearing Materials for Resistance to Wear Using a Hip Simulator
Lubricants, 2015 Electron beam crosslinked ultra high molecular weight polyethylene (UHMWPE) 32 mm cups with cobalt alloy femoral heads were compared with gamma-irradiation sterilized 26 mm cups and zirconia ceramic heads in a hip wear simulator.

Research on ultra-low wear of steel/steel based on water/Span 60 composite semi-solid lubricant
FrictionAdequate lubrication of the steel/steel interface is an effective way to reduce wear and prolong the service life of mechanical equipment. However, achieving the green ultra-low wear between steel and steel remains a challenge. In this work, a semi-solid

Macromolecular Materials and Engineering, 2009 AbstractThe incorporation of microcapsules containing lubricant oil into epoxy composites leads to materials with ultra‐low friction and wear performance. During sliding wear tests, the capsules are damaged by the asperities of the counterface, releasing the oil to the contact area.

Research on ultra low wear materials for energy conservation: Final report
, 1989 This report summarizes a set of friction and wear measurements for glassy carbon based materials run against a broad range of counterfaces in ball on disk wear machines. The carbon based materials were operated as both riders and disks. The principal runs employed 1 N contact load, and special runs for the carbon on its own kind extended the load to 20
