In high-temperature environments, the surface of alloy parts is easily oxidized, leading to performance degradation. This not only affects their service life, but may also cause equipment failure and safety risks. The coating prepared by laser cladding technology has the characteristics of dense structure, good bonding with the substrate, low dilution rate and deformation, and exhibits excellent oxidation resistance at high temperature. Therefore, this article provides a review of the high-temperature oxidation resistance of the coatings prepared by laser cladding, explores the effects of single element and rare earth oxides on the high-temperature oxidation resistance of laser cladding coatings, introduces the relevant research on new technologies and auxiliary fields, such as high-speed laser cladding, intense pulsed electron beam, ultrasonic vibration, and electromagnetic assistance, in improving the high-temperature oxidation resistance of laser cladding alloys, and summarizes and prospects the development trends of high-temperature oxidation resistance of laser cladding alloy coatings.
