Studies on the Bioceramic Coating on Titamium Substrate Including Silicon and Calcium by Micro-arc Oxidation and Osteoblasts Adhesion and Proliferation on the coating
This study used micro-arc oxidation technology for pure titanium alloy surface modification,which 400μm titanium beads were sintered into porous titanium in vacuum conditions,and produced silicon and calcium coatings.Scanning electron microscope(SEM),X-ray diffraction (XRD) and Energy dispersion spectrometer(EDS) were employed to investigate the surface morphology and phase composition of the coatings.The results are listed as follows:the main component of porous titanium MAO coating is anatase TiO2,and the coating introduced silicon and calcium element successfully.The proliferation ability of osteoblasts on the oxidized and unoxidized surface was determined by CCK-8 method,The results indicated that both the proliferation and adhesion ability of osteoblast on the oxidized surface were better than the unoxidized surface.
