Abstract
The present work focuses on the influence of copper complexes in the MAO electrolyte on the structure and wears resistance of ceramic coating on the surface of titanium alloy. The coatings composition and the morphologies were characterized using X-ray diffraction (XRD), energy dispersive spectroscopy (EDS) and scanning electron microscopy (SEM). It is shown that the working voltage of MAO reaction was lower after adding [Cu (NH3)4]2+ than adding EDTA-Cu. The color of ceramic coating is black (prepared in the electrolyte with [Cu (NH3)4]2+) and brown (prepared in the electrolyte with EDTA-Cu). The black coating contained rutile TiO2, anatase TiO2 and aluminium titanate (Al2TiO5), while the brown coating contained rutile and anatase only. The black coating which contained CuO compound was found to outperform brown coating in wear resistance.
