(Ti,M)C复式碳化物制备方法的研究进展

对当前(Ti,M)C碳化物的制备方法进行了综述,详细介绍了不同制备方法的制备过程及原理,对不同制备方法的优缺点进行了论述。碳热还原法是目前广泛使用的一种方法,能够制备复杂成分的(Ti,M)C,但该方法耗能大、工艺流程复杂;预合金化法能够制备某些特定成分的碳化物,但其使用范围受限;自蔓延高温合成法可以制备多种成分的(Ti,M)C,但大部分情况下需要预热且存在反应不完全的情况。目前没有一种制备方法同时具有高效、工艺流程简单、适用性强且产物纯度高等优点,对现有制备方法进行改进以满足工业化应用是(Ti,M)C复式碳化物的研究发展方向。

Research progress on preparation of (Ti,M)C composite carbides

The different methods for synthesizing (Ti,M)C carbides were summarized. The preparation process and principle of different preparation methods were introduced in detail,and the advantages and disadvantages of the methods were discussed. Carbon thermal reduction is one of the most widely used methods to prepare (Ti,M)C with complex component,but it has high energy consumption and complex process. Pre-alloying method can pre-pare some carbides with special components,but its use is limited. Self-propagating high temperature synthesis can prepare various kinds of (Ti,M)C,but most of them need to be preheated and the reaction is incomplete. Gen-erally speaking,there is no preparation method which has the advantages of high efficiency,simple process flow, strong applicability and high product purity,simultaneously. Improvement of the existing preparation methods to meet the industrial application is the research and development direction of (Ti,M)C composite carbide.
