AlON ceramic composite material and preparation method thereof
The invention belongs to the technical field of inorganic non-metallic materials, and particularly relates to an AlON ceramic composite material and a preparation method thereof. According to the invention, AlON, SiC and B4C powder are used as raw materials, and the AlON composite ceramic material is prepared by a hot pressed sintering method by adjusting the mass ratio of SiC to B4C. After the obtained product is statically oxidized for 40 hours in air at 1500 DEG C, the oxidation weight gain rate is reduced by 78.8%-85.7% compared with that of pure AlON ceramic, the bending strength at room temperature is 301-324 MPa, the fracture toughness is 1.40-1.51 MPa.m<1/2>, the oxidation resistance of the AlON material is greatly improved, and a reference is provided for further application of the AlON ceramic in the high-temperature field.
本发明属于无机非金属材料技术领域，具体涉及一种AlON陶瓷复合材料及其制备方法。本发明以AlON、SiC和B4C粉体为原料，通过调整SiC和B4C的质量配比，以热压烧结法制备出AlON复合陶瓷材料。所得产品在1500℃下空气中，静态氧化40h后，氧化增重率相对纯AlON陶瓷减低了78.8％～85.7％，室温下的抗弯强度为301～324MPa，断裂韧性为1.40～1.51MPa·m1/2，大大提升了AlON材料的抗氧化性能，为AlON陶瓷在高温领域的进一步应用提供了参考。
