9357496 Trumble This research is directed towards the liquid phase processing of advanced metal-ceramic composites. Poor wetting hampers the processing of many composite systems. Although interfacial chemical interactions are thought to promote wetting, systematic studies of their effects and associated microstructural development are lacking. Reaction-driven wetting is studied using the sessile drop technique. Infiltration of liquid metals into porous ceramics is included in the research. The role of chemical interactions in wetting phenomena is examined through critical experiment coupled with direct interfacial characterization using electron microscopy. %%% The knowledge generated in this program is fundamental to the understanding of the properties of metal-matrix composites. This understanding can be applied to tailoring the properties of these technologically useful materials. ***

9357496这项研究针对晚期金属陶瓷复合材料的液相加工。 润湿性不佳会加工许多复合系统。 尽管界面化学相互作用被认为可以促进润湿，但缺乏对其作用和相关微结构发展的系统研究。 使用无柄滴技术研究了反应驱动的润湿。 研究中包括将液体金属浸润到多孔陶瓷中。 化学相互作用在润湿现象中的作用通过批判性实验以及使用电子显微镜的直接界面表征来检查。 %%％该程序中产生的知识对于理解金属矩阵复合材料的性质至关重要。 这种理解可以应用于调整这些技术有用材料的性质。 ***
