The invention discloses a surface coating of a stamping part. The surface coating sequentially comprises a transition layer, a first wear-resistant layer and a second wear-resistant layer from insideto outside, wherein the transition layer is TiN or CrN, the first wear-resistant layer is a nano multi-layer formed by alternating the TiN, CrN and MoN, and the second wear-resistant layer is a mixedlayer of polytetrafluoroethylene and molybdenum disulfide. According to the surface coating of the stamping part, a mixture of the polytetrafluoroethylene and the molybdenum disulfide is added into the coating, so that the coating is stable in performance and does not react with a medium, and meanwhile, the wear-resistant coating is not influenced by environmental factors so that environment dielectric effects and various chemical corrosion can be effectively resisted; and the surface coating of the stamping part is high in wear resistance, corrosion-resistant and long in service life.
