Modern industry is developing rapidly. At the same time, we have higher and higher requirements for the performance of tools and abrasives, but there is always a contradiction between hardness and strength. Therefore, in order to improve performance, there is a hard coating technology for tools and abrasives.
As we all know, tool performance plays a decisive role in the machining process. Similarly, in industrial production, the performance of cutting tools and abrasives has a great impact on machining efficiency, accuracy and surface quality. However, the strength of raw materials with high hardness is low, and improving the strength often comes at the cost of reducing the hardness.
Therefore, in order to solve this contradiction and improve the performance of tools and abrasives, a variety of coating technologies can be used to coat one or more layers of materials with high hardness and high wear resistance on cemented carbide matrix. For tools, the coating on the surface of cemented carbide tools can be used as a chemical barrier and thermal barrier to reduce the wear of crescent depression of cemented carbide tools, significantly improve the machining efficiency, improve the machining accuracy, prolong the service life of tools, reduce the machining cost and improve the efficiency.
