Preparation method of high-strength ceramic-based composite material
The invention relates to the technical field of ceramic composite materials, in particular to a preparation method of a high-strength ceramic-based composite material. Comprising the following steps that silicon carbide ceramic particles, silicon nitride ceramic particles, submicron titanium nitride, an adhesive and an expansion monomer are mixed to obtain slurry, then the slurry is made into a mold with through holes, after sintering, quenching and tempering are conducted, high-chromium cast iron is melted and then poured, and the high-strength ceramic-based composite material is obtained. The high strength and high wear resistance of ceramic are combined with the toughness and bending resistance of metal, and the epoxy resin, the benzoxazine resin and the phenolic resin are mixed to serve as the adhesive, so that the densification degree is improved, and the material has excellent mechanical properties.
本发明涉及陶瓷复合材料技术领域，具体涉及一种高强度的陶瓷基复合材料的制备方法。包括以下步骤：将碳化硅陶瓷颗粒，氮化硅陶瓷颗粒，亚微米级氮化钛，粘接剂和膨胀单体混合得到浆料，再将浆料制成具有通孔的模具，经过烧结，淬火，回火后，再将高铬铸铁熔化后进行浇筑，得到高强度的陶瓷基复合材料，本发明将陶瓷的高强度和高耐磨性与金属的韧性以及抗弯性结合，并且将环氧树脂，苯并噁嗪树脂和酚醛树脂混合作为粘接剂，提高了其致密化程度，使得其具有优异的力学性能。
