    摘要:

    在電解液中添加HfO2對Ti-6Al-4V鈦合金進(jìn)行微弧氧化處理，通過表征微弧氧化膜表、截面形貌，膜層成分及電化學(xué)行為，并測量膜層厚度、硬度、粗糙度等參數(shù)來研究添加HfO2對鈦合金微弧氧化膜層特性的影響。結(jié)果表明：添加HfO2后，微弧氧化膜層主要成分是Al2TiO5、TiO2和γ-Al2O3。較合適濃度的HfO2能促進(jìn)成膜反應(yīng)，改善微弧氧化膜的微觀結(jié)構(gòu)，提高膜層的厚度、硬度并降低表面粗糙度，且膜層試樣具有雙層膜結(jié)構(gòu)，膜層試樣的耐腐蝕性能好于原基體。HfO2濃度為3.0g/L時所獲得的微弧氧化膜層綜合性能最佳。

    Abstract:

    The Ti-6Al-4V titanium alloy was treated with micro-arc oxidation by adding HfO2 into the electrolyte. The effect of adding HfO2 on the characteristics of the micro-arc oxidation film of titanium alloy was studied by characterizing the surface and cross-section morphology of the micro-arc oxidation film, the composition of the film and the electrochemical behavior, and measuring the thickness, hardness, roughness and other parameters of the film. The results show that after adding HfO2, the main components of the micro-arc oxidation film are Al2TiO5,TiO2 and γ-Al2O3.The appropriate concentration of HfO2 can promote the film-forming reaction, improve the microstructure of the micro-arc oxidation film, improve the thickness and hardness of the film and reduce the surface roughness. The film sample has a double-layer film structure, and the corrosion resistance of the film sample is better than the original substrate. When the concentration of HfO2 is 3.0g/L, the comprehensive performance of the micro-arc oxidation coating is the best.
