The invention discloses an abrasion-resistant coating for an automobile shell. The abrasion-resistant coating is applied to an automobile, and comprises an electroplating base layer, a functional intermediate layer and a surface layer which are sequentially disposed. The functional intermediate layer is an Al/WC/MoO2 intermediate layer, and the Al/WC/MoO2 intermediate layer is sprayed by any one of supersonic flame spraying, low pressure plasma spraying or inert gas protection plasma spraying technology. The electroplating base layer is a Cr-AlN layer formed by CKS composite plating. The abrasion-resistant coating for the automobile shell adopts a composite coating composed of metallic aluminum, tungsten carbide and molybdenum dioxide as the intermediate layer, and a coating with abrasionand corrosion resistance, good tribological properties and a lubrication action is obtained, so that traces are not prone to being left on the automobile shell when scratching.
