Alumina-based ceramic composite material and preparation method thereof
The invention relates to the technical field of material preparation, in particular to an alumina-based ceramic composite material and a preparation method thereof, and the alumina-based ceramic composite material comprises the following components in percentage by weight: 75-85% of alumina powder, 2-20% of carbide and 3-5% of pure metal. According to the invention, a certain amount of carbides, including one or more of titanium carbide, carbide or tantalum carbide, are added into high-purity aluminum oxide, so that compounding between the carbides and aluminum oxide is realized, and the strength, wear resistance, impact resistance and high-temperature resistance of the aluminum oxide-based ceramic composite material can be effectively improved; the aluminum oxide-based ceramic composite material can effectively overcome the inherent fatal weakness of brittleness of aluminum oxide-based ceramic in the prior art, so that the application range of the aluminum oxide-based ceramic material is wider. The alumina-based ceramic composite material has the advantages of high strength and high density.
本发明涉及材料制备技术领域，具体涉及一种氧化铝基陶瓷复合材料及其制备方法，按重量分数计组成包括：75％‑85％的氧化铝粉末，2％‑20％的碳化物和3％‑5％的纯金属组成。本发明通过在高纯度的氧化铝之中添加一定量的碳化物，包括碳化钛、碳化物或碳化钽中的一种或多种，实现碳化物与氧化铝之间的复合，可以有效的提高氧化铝基陶瓷复合材料的强度、耐磨性、抗冲击性能和耐高温性能，使得氧化铝基陶瓷复合材料可以有效的克服现有技术氧化铝基陶瓷具有脆性这一固有的致命弱点，从而使得氧化铝基陶瓷材料使用范围更加的广泛。本发明的氧化铝基陶瓷复合材料具有高强度和高密度的优点。
