Paper Title:
Characterization of Micro-Arc Oxidation Coatings Formed on Biomedical Ni-Cr-Mo Alloy
  Abstract

In this paper, the micro-arc oxidation coatings formed on biomedical Ni-Cr-Mo alloy were characterized by surface and cross-sectional morphologies, chemical and phase compositions and corrosion resistance using scanning electron microscopy (SEM), Energy dispersive X-ray spectrometer (EDS), X-ray diffraction (XRD) and potentiodynamic polarization test, respectively. The results show that the coating is mainly composed of γ-Al2O3 crystal phase with a little Ni content. The coating possesses a typical porous surface and has a thickness of ~6 μm. The corrosion resistance of the coated sample is greatly improved compared with the uncoated Ni-Cr-Mo alloy.
