为改善铝合金零部件的摩擦磨损特性,采用微弧氧化和射频磁控溅射技术,在2A12铝合金表面制备Al_2O_3/CrN_x复合膜.用X射线衍射仪、涡流测厚仪、纳米硬度仪、微摩擦磨损试验机、非接触表面三维形貌仪及扫描电镜对Al_2O_3涂层及复合膜的相组成、膜厚、纳米硬度、摩擦磨损特性和磨痕形貌等进行了研究.实验结果表明:32μm厚的多孔Al_2O_3陶瓷涂层由α-Al_2O_3和γ-Al_2O_3相组成,外层1.2μm厚的CrN_x膜由单质Cr,Cr_2N和CrN相组成;Al_2O_3涂层及Al_2O_3/CrN_x复合膜的摩擦因数和磨损率都随法向载荷的增加而增大,在相同实验参数下,复合膜的摩擦因数和磨损率都远小于Al_2O_3涂层的,这表明在Al_2O_3涂层表面沉积CrN_x膜能明显改善其摩擦磨损特性,将延长对偶件的使用寿命.
