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 technol...
