Abstract The popular materials of laser cladding coatings are reviewed. The dominating problems to limit application of laser cladding materials and general countermeasures to them are put forward. Some principles for designing and developing laser cladding materials are provided. It states that the material is a vital factor to affect the technical and application performances of the laser cladding coating. And the important developing direction for laser cladding technology is to research and develop special powder materials.
