Survey assesses tribological properties and wear rates of joint replacement liners, highlighting key differences.
The survey assessed tribological properties of the materials based on ultra-high-molecular-weight polyethylene for joint replacement liners by several major manufacturers. Being their crucial parameter, the mass wear rates were compared. Scanning electron microscopy was used to assess the metamorphosis of the materials surface after friction. With its help, the morphology of the surfaces with wear particles was assessed. Using IR spectroscopy, oxygen-containing functional groups were identified on the friction surfaces, which were formed during tribooxidative processes. The tribological properties of the materials were compared with their thermal and structural properties.
