The wear resistance of cemented carbide is closely related to the service life of cemented carbide tools.
The wear resistance of cemented carbide tools mainly depends on factors such as the hardness, chemical composition and microstructure of the material.
The higher the hardness of the material, the better the wear resistance and the longer the service life of the tool. Generally speaking, the hardness of cemented carbide materials should be greater than the hardness of the workpiece material, and the hardness at room temperature should be above 60HRC.
In addition, the microstructure of the material also affects the wear resistance. The higher the hardness, the greater the number, the finer the grains, and the more evenly distributed the hard points in the cemented carbide, the better the wear resistance.
Therefore, improving the wear resistance of carbide can effectively extend the service life of carbide cutting tools.
