Laser cladding refers to the process method of placing the selected coating material on the surface of the coated substrate in different feeding methods to melt a thin layer on the surface of the substrate at the same time, and forming a surface coating with very low dilution after rapid solidification, and forming a metallurgical combination with the substrate to significantly improve the wear resistance, corrosion resistance, heat resistance, oxidation resistance and electrical characteristics of the base surface. Thus, the purpose of surface modification or repair is achieved, which not only meets the requirements of specific properties of the material surface, but also saves a lot of valuable elements.
Application
1.Tool manufacturing: M4 metal powder is often used to manufacture various cutting tools, such as planers, turning tools, milling cutters, etc., which can maintain stable cutting performance under high-speed cutting conditions.
2. Drill bit manufacturing: Because M4 high-speed steel has high hardness and wear resistance, it is suitable for manufacturing various drill bits, such as center drills, thread drills, etc., and can maintain a long service life during the drilling process.
3. Tool coating: M4 metal powder can also be used to prepare tool coatings to improve the wear resistance and cutting performance of tools through surface spraying and other processes. In general, M4 metal powder is suitable for manufacturing various cutting tools due to its high hardness, wear resistance and thermal stability, and is widely used in metal processing, machinery manufacturing, aerospace and other fields.
