The invention discloses a three-liquid two-phase
bimetal-ZTA
ceramic composite material impact crusher plate hammer and a manufacturing method thereof.The three-liquid two-phase
bimetal-ZTA
ceramic composite material impact crusher plate hammer comprises martensitic steel, high-
chromium cast iron and a high-
chromium cast iron-ZTA
composite cylinder, the martensitic steel is located in the middle, the high-
chromium cast iron is located on the two sides of the martensitic steel, and the high-chromium cast iron-ZTA
composite cylinder is located on the outermost side of the high-chromium cast iron; the high-chromium cast iron-ZTA
composite cylinder is formed in the mode that high-chromium cast
iron powder is melted and connected in a bridging mode to evenly wrap ZTA, the high-chromium cast iron-ZTA composite cylinder is evenly embedded into a mold in advance, and in the high-chromium cast iron molten iron
casting process, the high-chromium cast iron-ZTA composite cylinder is formed in the mode that high-chromium cast
iron powder is melted and connected in a bridging mode to evenly wrap ZTA. And the high-chromium cast iron-ZTA composite cylinder is automatically embedded into the high-chromium cast iron on the outermost side. The high-chromium cast iron and the martensitic steel are bonded in a
diffusion metallurgical mode, and the high-chromium cast iron and the high-chromium cast iron-ZTA composite cylinder are bonded in a
diffusion metallurgical mode. According to the plate hammer of the
impact crusher, the martensitic cast steel, the high-chromium cast iron and the ZTA
ceramic are organically combined in a mutual gradient mode, and ultrahigh
wear resistance is obtained.
