Abstract  Wear-resistant and corrosion-resistant coatings manufactured by laser cladding technology is used to solve the wear and corrosion problems of parts in harsh environments. It has good prospects for development. In this paper, the development history of laser cladding technology is briefly introduced, and the research progress of the influence of laser cladding technology on the preparation of wear-resistant and corrosion-resistant coatings is summarized emphatically at home and abroad, as well as the relationship between the change of molten pool and laser cladding process parameters and the structure properties of the cladding layer. The research progress of laser cladding technology for wear-resistant and corrosion-resistant coatings in specific application parts and working conditions is also described, including parts of hydraulic engineering equipment, aerospace equipment, petroleum mining equipment, etc. Finally, it summarizes the key issues that restrict the comprehensive industrial application of the technology, as well as the research directions that need to be carried out in terms of process and equipment.
