| Abstract: | In order to improve the hardness and wear resistance of the surface of components in the oil-drilling
industry and increase the service life of the components, three iron-based laser powders containing Cr and V
elements are designed and developed. The coating is prepared by laser cladding processing technology. The phase,
hardness and friction and wear properties of the iron-based laser coating are tested, and the hardness is up to 60
HRC, a friction coefficient of 0.6094, and a wear volume of 0.0007 g under a load of 50N in 15 minutes. A high
wear-resistant iron-based laser coating was developed that could meet the demands of the oil drilling industry for
coatings with high hardness, high wear resistance and long life. |
