    Abstract
  • The application of the cast WC, the Co powder coated cast WC and the Ni powder coated cast WC particles in diamond saw blades were studied, and their effects on the mechanical properties, the micro morphologies and the cutting properties of the diamond saw blade matrix were explored. The results show that when the mass ratio of the three kinds of WC material to the metal powder is 3∶1, the hardness of the three kinds of matrix is equivalent. The bending strength of the matrix containing Co powder coated cast WC is the highest, the interface between the WC particles and the matrix is the closest, and the microstructure of the matrix is the densest. The bending strength of the matrix containing Ni powder coated cast WC is the second. The matrix with only cast WC has the worst bending strength. Compared with the saw blade with only cast WC added, the cutting life of the saw blade with Co powder coated cast WC is the longest and increases by 40%.
