一种Cr-C-N基金属陶瓷及其制备方法
摘要：
本发明提供了一种Cr‑C‑N基金属陶瓷，涉及金属陶瓷材料技术领域。本发明提供的金属陶瓷由包括以下质量百分含量的组分制备得到：金属粉末10～40％，碳化物粉末5～30％，余量为Cr‑C‑N硬质相粉末；所述Cr‑C‑N硬质相粉末是由Cr、C和N三种元素形成的单相固溶体；所述Cr‑C‑N硬质相粉末中C的质量百分含量为0.1～9％，N的质量百分含量为0.1～11％，余量为Cr。本发明提供的Cr‑C‑N基金属陶瓷具有优异的硬度、韧性、热稳定性、耐磨和耐腐蚀性等综合性能，且烧结稳定性好。本发明还提供了所述金属陶瓷的制备方法，本发明提供的制备方法过程简单，条件易控，利于工业化推广。
摘要（英）：

The invention provides a Cr-C-N-based metal ceramic, and relates to the technical field of metal ceramic materials. The Cr-C-N-based metal ceramic is prepared by the following components in mass percentage content: 10-40% of metal powder, 5-30% of carbide powder, and the balance Cr-C-N hard-phase powder, the Cr-C-N hard-phase powder is the single-phase solid solution formed by three elements of Cr, C and N in mass percentage: 0.1-9% of C, 0.1-11% of N and the balance of Cr.. The Cr-C-N-based metal ceramic has the comprehensive properties such as the excellent hardness, toughness, thermal stability, wear resistance and corrosion resistance, and the sintering stability is high. The invention further provides a preparation method for the metal ceramic, and the preparation method is simple inprocess, the condition is controllable, and the popularization of the industrialization is benefited.
