With the development of CNC machine tools, traditional standardized tools can not meet the requirements of modern manufacturing industry for improving efficiency and reducing costs. Tungsten carbide coating has the advantages of high hardness, excellent wear resistance and long life, which promotes the rapid development of CNC tools.
Coated tungsten carbide materials are mainly divided into coatings and cemented carbide matrix. The process of coating is a process of physicochemical reaction and film formation. The performance and surface state of the substrate must meet the requirements of the coating. The coating must be combined with the appropriate substrate to achieve the desired performance.
