简介：陶器的涂层被微等离子区氧化(军邮局)在NaAlO2答案在Ti-6A14V合金上准备。涂的样品和底层的盐水花测试在一台盐水花测试机器被执行。涂层的阶段作文和表面形态学被XRD和SEM调查。严重腐蚀发生在底层表面上，当涂的样品上没有明显的腐蚀现象时。涂层由Al2TiO5和小-Al2O3和金红石TiO2组成，并且盐水花测试没改变涂层的作文。涂层的重量损失率与因为涂层的密度和厚度的增加，增加军邮局时间减少了。涂层的表面形态学被盐水花腐蚀测试影响。在涂的样品之中，为2h作好准备的涂层在盐水花测试下面有最好的腐蚀抵抗。

简介：钛氧化物涂层被微弧的氧化(毛)在Ti-2Al-2.5Zr合金底层上综合技术。涂层的表面特征被扫描电子显微镜学学习。当分泌物隧道尺寸随对待时间的增加清楚地增加时，Ti-2Al-2.5Zr合金的微弧的分泌物隧道减少。随涂层厚度的增加，多孔的层厚度显然增加。涂层的表面层的阶段作文被X光检查衍射和X光检查光电子光谱学评估。XRD和XPS分析的结果证明毛涂层主要由锐钛矿和金红石TiO2组成。
