Preparation method of ablation-resistant antioxidant carbon-ceramic composite material matrix
The invention discloses a preparation method of an ablation-resistant antioxidant carbon-ceramic composite material matrix, and belongs to the technical field of preparation of inorganic nonmetal graphite materials. The problems of low rotating speed, low specific pressure, low friction rate, low corrosion resistance and the like of the existing graphite material are solved. Artificial graphite powder and superfine pitch coke powder are used as main raw materials, mesocarbon microbeads, zirconium carbide (ZrC) and boron nitride (BN) are used as auxiliary materials for preparation, three-stage production is adopted, the ablation resistance and oxidation resistance of a graphite matrix are greatly improved, the microstructure of the material is improved through isostatic pressing, and the performance of the material is improved. Under the condition that the appearance shape is not changed, the distance between molecules is shortened, the density is increased, so that the physical property of the material is improved, and the obtained graphite matrix has high volume density, high graphitization degree, high corrosion resistance and high oxidation resistance.
