中文摘要：

为改善镁合金有机电泳涂层耐磨性能，通过硅烷偶联剂改性陶瓷粉体，并将陶瓷粉体充分分散于电泳漆中制得镁合金阴极电泳复合涂层，用铅笔硬度、摩擦磨损测试系统、画图附着力方法、氯离子腐蚀试验、分别评价比较了阴极电泳涂层和加粉体后复合涂层的硬度、附着力、耐蚀性和耐磨性能。结果表明：硅烷改性Al2O3粉体的阴极电泳有机无机复合涂层厚度与不加粉体的相当，粉体的加入不会改变涂层与基体的附着力和耐蚀性，但可以增加涂层的硬度，极大地提高涂层的耐磨性。

英文摘要：

The cathodic electrodeposition coatings（E-coatings） with silane modifying ceramics are prepared on magnesium alloy for improving the abrasion resistance of organic E-coating. corrosion resistance, circle-drawing method and abrasion resistance are evaluated by Hardness, adhesion, pencil hardness, UMT abrasion test system, and Machu test. The results show that the abrasion resistance and hardness of E-coatings are enhanced by adding Al2O3 ceramic powders. Meanwhile, corrosion resistance and adhesion of E-coatings remain unchanged.
