Set of advanced computer-aided design, computer-aided manufacturing, powder gold treatment, laser processing and other laser remanufacturing technology is a new concept of advanced repair technology, it is a variety of technologies in one, not only can make the damaged parts recover the shape of the size, but also can make its performance reach or even exceed the level of new products, is the development direction of major engineering equipment repair. Laser cladding technology is the core of laser remanufacturing technology, which refers to the process method of placing the selected coating material in different feeding methods on the surface of the coated substrate, melting it and the thin layer on the surface of the substrate by laser irradiation, and forming a coating with extremely low dilution and metallurgical combination with the matrix metal after rapid solidification, thereby significantly improving the wear resistance, corrosion resistance, heat resistance, oxidation resistance and other properties of the substrate material surface.
