Abstract
The tribotechnical properties of hydroxyapatite (HA) nanocomposite based on ultra-high molecular weight polyethylene (UHMWPE) under dry sliding and lubrication of distilled water and plasma blood was investigated with block-on-ring. It was shown that modification of UHMWPE by HA nanoparticles within range of 0.1–0.5 wt.% results in decrease of wear intensity at dry sliding up to 3 times. The under lubrication, wear intensity of pure UHMWPE and nanocomposite are deceased up to 50–70% as compared with under dry sliding. Permolecular structure of pure UHMWPE and nanocomposite are spherulitic structure, which nanoparticle does not alter the nature of the permolecular structure, and homogeneously dispersed in the UHMWPE matrix.
