In the field of material crushing of solid waste treatment of metallurgy, mines, cement and construction waste, because parts are in high-hardness materials and high-rotation or high-impact severe working conditions, the alloy material for preparing the parts of the crushing equipment is cracked, damaged and peeled under the strong-impact working condition, and the service life of the parts is shortened. Therefore, it is required to improve the toughness of the binder phase of the alloy material and the bonding strength between the binder phase and the base material so that the working surface and the matrix structure of the crushing equipment part have the characteristics of resisting abrasive wear and erosive wear at the same time.
