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.
