Research progress and Prospect of Laser Cladding Technology

Abstract Laser cladding technology is an advanced material surface modification technology, which has the advantages of a small dilution rate, a dense microstructure of the cladding layer, a good combination between coating and substrate, and no pollution of the working environment. The research progress of laser cladding is reviewed from three aspects: background types, basic principles, and research status. In the background category, the preset coating method and synchronous powder feeding method used in laser cladding technology are described. The research status of laser cladding technology is summarized from the aspects of cladding material, performance, and industrial application. Finally, some suggestions are put forward to obtain the cladding layer with no crack and good mechanical properties, and more technologies and laser cladding technology are expected to be combined in the future.
