Surface micro/nanostructure on the TZ30 alloy regulated by the electrochemical etching method

The Ti‐30Zr‐5Al‐3V titanium alloy has an ultra‐low Young's modulus. So, it promises great application potential as a hard‐tissue implanted biomaterial. However, its surface performances need to be improved before clinical applications. In this work, a carbonated hydroxyapatite film is deposited on the surface of Ti‐30Zr‐5Al‐3V bio‐alloy using electrochemical methods. Microstructure, film‐substrate adhesion, and electrochemical corrosion behavior of carbonated hydroxyapatite deposited specimens in Ringer's solution are investigated. A homogeneous, dense, and fully covered carbonated hydroxyapatite film forms on the surface after depositing at 3 V, 90 °C for 120 minutes. The formation mechanism of the carbonated hydroxyapatite film on the micro‐nano structure surface is revealed. The corrosion performance of carbonated hydroxyapatite deposited specimens in Ringer's solution is evaluated by using potentiodynamic polarization curves. The carbonated hydroxyapatite deposition obviously enhanced the corrosion resistance of the Ti‐30Zr‐5Al‐3V bio‐alloy.
