Hydrogenated diamond-like carbon films deposited on UHMW-PEAnnett Dorner-Reisel1, Guido Reisel2, Gert Irmer3, and •Christian Röder31Förderung der Materialent-wicklung und Technologie Chemnitz e.V., Germany — 2Sulzer Metco WOKA GmbH, Barchfeld, Germany — 3Institut für Theoretische Physik, TU Bergakademie Freiberg, Germany

The wear resistance of ultrahigh-molecular weight polyethylene (UHMW-PE) can be increased by an optimized hydrogenated amorphous diamond-like carbon coating (DLC, a-C:H). Possible applications are inlays in endoprosthetics (artificial finger, knee or hip joints, etc.). The deposition of the hydrogenated DLC coatings with thicknesses between 1 µm and 3 µm was carried out by plasma enhanced chemical vapour deposition (r.f.-PECVD). In order to verify the cohesive and adhesive adherence of the DLC films, several tribological tests were performed (scratch test, pin-on-disk-test, simulated knee prostheses wear test, etc.). The microstructure of the coatings was analysed with scanning electron microscopy, atomic force microscopy and Raman spectroscopy.
