Abstract

A method for manufacturing a metal object having a solid lubricating surface layer includes: providing a metal blank having a surface; providing a plurality of microparticles and solid lubricating powder, and mixing them together, wherein the microparticles have a hardness greater than that of the surface; and projecting the microparticles and the solid lubricating powder onto the surface, wherein the microparticles cause plastic flow on the surface to form a compressive stress layer, and the solid lubricating powder adheres to the compressive stress layer to form a solid lubricating surface layer.
