采用微弧氧化方法在不同水溶液中制备了Ti6 Al 4V合金表面Al-C、Si-P-Al和P-F-Al三种功能涂层。利用扫描电镜、X射线衍射仪和能谱仪对涂层的组织、物相和化学成分进行了分析。通过剪切、拉伸和热震试验，揭示了涂层的界面粘结破坏模式。定量剪切试验表明，Al-C、Si-P-Al和P-F-Al涂层的结合强度分别为110、70和40 MPa。拉伸试验表明，微弧氧化处理对基体钛合金的力学性能没有明显影响。涂层在经受相同的3.0%拉伸伸长率后的失效观察结果与剪切试验的结果非常一致。热循环试验表明，所有涂层均具有良好的抗热震性能。
Three functional coatings (namely Al-C, Si-P-Al and P-F-Al coating) were fabricated by microarc oxidation method on Ti6Al4V alloy in different aqueous solutions. The microstructure, phase and chemical composition of coatings were investigated using scanning electron microscope, X-ray diffraction and energy dispersive spectroscopy. The interface adhesion failure mode of the coating is revealed by shear, tensile and thermal shock methods. The coatings exhibit high adhesion strength by the quantitative shearing test, registering as 110, 70, and 40MPa for Al-C, Si-P-Al and P-F-Al coating, respectively. The tensile test of the coated samples shows that microarc oxidation treatment does not significantly deteriorate mechanical properties of substrate titanium alloy. The observations of the coating failure after subjected to the identical tensile elongation of 3.0% are well in agreement with those results of the shear test. The thermal cycle test indicates that all the coatings have good anti-thermal shocking properties.
