More Information
Summary:The invention discloses a gradient porous ceramic preform, an aluminum alloy toughened ceramic composite material and preparation. The gradient porous ceramic preform comprises a first porous ceramic preform layer, a second porous ceramic preformlayer, a third porous ceramic preform layer, a fourth porous ceramic preform layer and a fifth porous ceramic preform layer which are sequentially arranged; the porosity of the first porous ceramic preform layer, the porosity of the second porous ceramic preform layer, the porosity of the third porous ceramic preform layer, the porosity of the fourth porous ceramic preform layer and the porosity of the fifth porous ceramic preform layer are sequentially increased. The gradient porous ceramic preform has good corrosion resistance, high specific modulus, high specific strength and high wear resistance through a five-layer stacked structure, can show good performance in a high-temperature environment, meets the performance requirements of safety tongs wedges, and has wid
