中文摘要：

根据固体与分子经验电子理论（EET）以及异相界面电子结构模型，系统计算了（Ti，Me）C／Fe系列金属陶瓷界面电子结构（Me=Mo、W、V、Nb、Ta），初步分析了其界面电子结构与界面润湿、金属陶瓷力学性能之间的关系，结果表明：Me的添加使TiC／Fe金属陶瓷界面电子密度增大，界面润湿改善，改善界面润湿的能力从大到小排列为：Mo、W〉Nb、Ta〉V：另外，Me的加入使TiC／Fe金属陶瓷界面电子密度差增大，界面应力增大，有利于陶瓷晶粒的细化和提高界面结合强度，Mo、W添加剂能有效提高TiC／Fe金属陶瓷界面强韧性。

英文摘要：

Based on the empirical electron theory （EET） of solids and molecules and the valence electron theory of biphase interface, the interracial valence electron structure of （Ti, Me）C/Fe system （Me=Mo, W, V, Nb, Ta） was calculated, and the relationships between interracial valence electron structure and properties were analysed. The results indicate that Me could improve TiC/Fe eermet＇s interracial electron density and interface grain-refining and interracial co electron density difference. It is beneficial to the improvements of interfacial wettability, ceramic njunction and their ability sequence is Mo, W〉Nb, Ta〉V; in addition, Mo and W can always improve the interracial obdurability of TiC/Fe cermet.
