Title:
WC-NI WEAR-RESISTANT COATING ON 316L STAINLESS STEEL SURFACE AND PREPARATION METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2024/077654
Kind Code:
A1
Abstract:
A WC-Ni wear-resistant coating on a 316L stainless steel surface and a preparation method therefor, relating to a laser cladding material. The WC-Ni wear-resistant coating comprises a substrate and the WC-Ni wear-resistant coating located on the surface of the substrate, and comprises a surface layer and a transition layer arranged in sequence from top to bottom; the surface layer is formed after performing laser cladding by using WC powder, and the WC powder contains 57-63% of WC according to the mass fraction; and the transition layer is formed after performing laser cladding by using Ni625 powder. The WC-Ni wear-resistant coating is prepared by performing laser cladding by using the WC powder and the Ni625 powder, and the composite coating combines the excellent characteristics of metal with the characteristics of a ceramic material, such that the quality, wear resistance, hardness, and strength of the 316L stainless steel surface can be effectively improved, thereby enabling the 316L stainless steel surface to be applicable to more severe working environments.
