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
