合金钢陶瓷复合铸造

DJM采用金属陶瓷颗粒为增强相、合金钢为基体金属、利用纳米陶瓷提高耐磨衬板金属基体的强度，在耐磨衬板易磨损部位熔铸增强相-陶瓷颗粒预制体，熔铸过程中基体金属与合金化后的陶瓷颗粒在金属液高温作用下实现冶金结合、从而获得硬度呈阶梯分布的金属基陶瓷复合层，大幅提高耐磨性能、冲击值超过50J/CM2，抗冲击，无断裂风险，塑性变形小，可焊接再加工，使用寿命是传统产品的1-3倍

DJM uses cermet particles as the reinforcement phase and alloy steel as the matrix metal, and uses Nano Ceramic to improve the strength of the metal matrix of the wear-resistant lining plate. The reinforcement phase - ceramic particle preform is cast in the wear-resistant lining plate. In the process of melting and casting, the matrix metal and alloyed ceramic particles achieve metallurgical combination under the action of metal liquid at high temperature, so as to obtain the metal base ceramic composite layer with a ladder of hardness distribution, which greatly improves the wear resistance, the impact value exceeds 50J/CM2, the impact resistance, no fracture risk, the plastic deformation is small, Weldable and reprocessable、and the service life is 1-3 times that of traditional products
