The Influences of Frequency on the Fabrication and Structural Studies of Micro-Arc Oxidization Ceramic Films Formed on Pure Titanium

摘要：

　　The porous oxide TiO2 ceramic film containing Ca and P is fabricated on the surface of pure titanium in the electrolyte of C4H6CaO4-NaH2PO4 by micro-arc oxidation (MAO) method.The microscopic structure, elemental composition and phase components of Ceramic Film are studied with scanning electron microscopy(SEM), energy dispersive spectroscopy (EDS), X-ray diffraction (XRD), 3D profilometer and etc.Results indicate that the ceramic film on pure titanium by micro-arc oxidation is a porous mixed crystal structure which contains anatase TiO2 and futile TiO2, and that the film is mainly composed of such elements as Ti, O, Ca and P.With frequency increasing, the number of micropores increases, the hole is decreased in diameter, porosity and roughness, and the surface is more smooth.The increase of frequencies makes the ratio of Ca/P decrease, the relative content of anatase TiO2 increase and rutile TiO2 decrease.
