The results show that in the applied load range of 10250 N, the mass loss rate of coated AZ91D alloy can be identified to three stages, which are related with whether the coating is worn out. Abrasion is the main mechanism for the coated alloy. The friction coefficient of the coated alloy during sliding wear appears oscillation before it reaches a constant value, which is close to the μ value of the matrix alloy. The mass loss rate of coated alloy increases slightly with increasing applied load when the applied load is more than 150 N because of high plastic deformation accommodation on the matrix alloy surface.

结果表明：根据载荷大小，涂层处理后AZ91D镁合金的磨损行为明显分为3个阶段，这些阶段同陶瓷层是否磨穿密切相关；微弧氧化涂层AZ91D镁合金的磨损机理主要是磨粒磨损；受表面状况的影响，陶瓷涂层的摩擦因数在 0.20~0.45 间波动；在较高载荷下，涂层被磨穿后，涂层的摩擦因数趋于基体合金的摩擦因数，涂层合金的表面变形能力提高，该阶段质量磨损速率随载荷增加，趋势变得缓慢。
