Study on Surface Characterization and Properties of Three Dimensional Nano-Porous Titanium Film

A Type of Three-Dimensional Nano-Porous Film on Titanium Was Successfully Prepared by Alkali Treatment. the Microstructure, Contact Angle and Surface Energy of the Film Were Investigated Using Scanning Electron Microscopy (SEM) and Contact Angle Meter. the Biomineralization of the Nano-Porous Titanium Was Studied in Vitro by Soaking in Simulated Body Fluid (SBF). the Experiment Results Demonstrated that Bone-Like Apatite Could Be Induced on Nano-Porous Titanium Surface, and the Apatite Crystals on Nano-Porous Titanium Surface Were Superior in Number and Higher in Crystallinity to that on Titanium Chemically Polished.
