Study of the in vitro corrosion resistance and cytotoxicity of a novel TiNbTaZr alloy

摘要：

　　β type titanium alloys have recently attracted much attention because of its low elastic modulus,high corrosion resistance and good biocompatibility.A novel β type Ti35Nb2Ta3Zr alloy with low modulus (48GPa) was fabricated using vacuum consumable arc melting furnace.In current study,the corrosion resistance and cytotoxicity of Ti35Nb2Ta3Zr were evaluated.The open circuit potential,electrochemical impedance spectroscopy (EIS) and potentiodynamic polarization methods were used to determine the corrosion resistance.In Ringers solution,Ti35Nb2Ta3Zr alloy exhibited better corrosion resistance,comparable to that of Ti6Al4V and Ti.The cytotoxicity tests indicated that the biocompatibility of Ti35Nb2Ta3Zr was as good as Ti and Ti6Al4V,which have been widely used in biomedical fields.Based on corrosion resistance and cytotoxicity,the novel β type Ti35Nb2Ta3Zr alloy can be considered as a potential biomaterial.
