The invention discloses a method for preparing an antifriction wear-resistant coating on a metal matrix surface. The method comprises the following steps: (I) uniformly mixing wear-resistant powder with metal powder to obtain cladding powder; (II) performing laser cladding on the metal matrix surface by use of the cladding powder to form multiple cladding belts in horizontal-longitudinal crossing, wherein the cladding belts in horizontal-longitudinal crossing form a cladding skeleton of a mesh structure; and (III) filling the metal matrix surface with a lubricating phase, and polishing to obtain the antifriction wear-resistant coating on the metal matrix surface. According to the method disclosed by the invention, the cladding skeleton prepared on the metal matrix surface through the laser cladding process has a remarkably high hardness value; the cladding skeleton can realize a load dispersing function in a wear process to effectively prevent accumulation of plastic deformation on the metal matrix surface; and meanwhile, the mesh structure of the cladding skeleton realizes a support effect on the follow-up film forming process of the lubricating phase.
