Document Type and Number:
WIPO Patent Application WO/2023/138145
Kind Code:
A1
Abstract:
The present invention relates to the technical field of friction and wear. Disclosed is a method for improving anti-friction and anti-wear properties of a substrate. The method of the present invention comprises: first, cladding the surface of a substrate with alloy powder to form a cladding layer; and then, performing texturing and sulfurizing treatment on the cladding layer in sequence to form a textured ion-sulfurized cladding layer having anti-friction and anti-wear properties on the surface of the substrate, so that the anti-friction and anti-wear properties of the substrate are improved, the use efficiency of the substrate is improved, and the service life of the substrate is prolonged.
