Microstructure and Mechanical Properties and Corrosion Behavior of Ti-Mo-Sn Alloys
The phase constitution, mechanical properties, and corrosion behavior of TiMoSn alloys were investigated by means of XRD, tensile test, electrochemical measurement and XPS techniques. The XRD analysis results showed that at room temperature TiMoSn alloys are mainly composed of β phase, with minor content of α" phase, in as-cast and solid solution treated conditions. The tensile test results indicate that the elastic moduli of the Ti-Mo-Sn alloys are in the range of 52~74GPa. The electrochemical measurement results indicate that TiMoSn alloys have excellent corrosion resistance in simulated body fluid. The XPS analysis results reveal that the passive films of TiMoSn alloys after polarization consist of TiO2, SnO2 and Mo2O5.
