An Effective Approach to Improve the Oxidation Resistance of Ti-6AI-4V Alloy by Combination of Phosphorization and Silica Coating
A very effective approach to improve the oxidation resistance of Ti-6A1-4V alloy was proposed. The Ti6A1-4V alloy was firstly phosphated and then coated by silica using sol-gel dip-coating technique. A duplex layer of TiP2O7 and amorphous silica was synthesized at the alloy surface. The isothermal and cyclic oxidation behavior of the treated alloy with silica coating and the corresponding bare alloy was investigated at 600 °C in static air to investigate the synergetic effect of phosphorization and amorphous SiO2 coating on the oxidation resistance of the alloy. The isothermal and cyclic oxidation resistances of the alloy were greatly improved.
