Laser cladding technology is an excellent surface modification method，which can generate dense ceramic coatings on the surface of the substrate and also achieve on-site repair of wear，corrosion and other damages，so that the parts can be kept in service without replacement，which greatly reduces the maintenance cost.This paper first introduces the classification of laser cladding technology and the laser cladding ceramic coatings，then elaborates on the numerical simulation and the performance optimization method of laser cladding ceramic coating，finally summarizes the research direction of laser cladding ceramic coating and looks forward to the problems and improvement measures in research and development and industrial production.
