多物理场作用下金属在碳/碳化物陶瓷表面的润湿及界面行为

以金属-碳及碳化物陶瓷高温下等温润湿的研究为基础，选取惰性润湿，反应润湿和吸附润湿中的典型体系作为研究对象；引入电流，电场及磁场作为外加物理场(源)，通过物理场参量的变化，考察由此引起的润湿行为及界面结构的演变；旨在揭示外加物理场(源)作用于高温下金属与非金属润湿的内在控制机理，建立相应润湿行为、界面结构与外加物理场(源)的耦合关系和铺展动力学模型；完善并提出高温下以液-固两相为基础的复合材料制备工艺中控制界面性质的理论基础及优化工艺的方法。本项研究对于实现金属基复合材料界面设计与可控，发展先进的复合材料制备技术具有重要的理论和实际应用意义。

Base on the research on the wettability of carbon or carbide ceramics by molten metals at high temperatures, typical systems for inert wetting, reactive wetting and adsorption wetting were selected. The electric current, electric and magnetic fields were also added as the extra physic fields (or sources). The wetting behavior and interfacial structure evolution were studied. The main purposes of this study are to reveal the controlled mechanism of wettability under multi-physics field, and then to connect the relation of wetting behavior, interfacial structures and parameters of multi-physics field. Base on above, the basic theories of interfacial property control for the fabrication of MMCs would be replenished and a new way for the optimization in the process would also be proposed. This project would be of great significance for improving of the preparation technology for composites by designed interface, also for developing a novel preparation technology.
