In vitro evaluation of the tribological response of Mo-doped graphite-like carbon film in different biological media

Journal Article


Abstract


  • Complicated tribochemical reactions with the

    surrounding media often occur at the prosthesis material, which

    is a dominant factor causing the premature failure in revision

    surgery. Graphite-like carbon (GLC) film has been proven to be

    an excellent tribological adaption to water-based media, and this

    work focused on the friction and wear behavior of Mo-doped GLC

    (Mo-GLC)-coated poly(aryl ether ether ketone) sliding against

    Al2O3 counterpart in physiological saline, simulated body fluid, and

    fetal bovine serum (FBS), which mainly emphasized the interface

    interactions of the prosthetic materials/lubricant. Results showed

    different tribological responses of Mo-GLC/Al2O3 pairs strongly correlated with the interfacial reactions of the contacting area.

    Particularly, a transfer layer was believed to be responsible for the excellent wear reduction of Mo-GLC/Al2O3 pair in FBS

    medium, in which graphitic carbon and protein species were contained. The wear mechanisms are tentatively discussed according

    to the morphologies and chemical compositions of the worn surfaces examined by scanning electron microscope as well as X-ray

    photoelectron spectroscopy
