production of composites materrials by evaluating wettability and joinability between metal and ceramics

了解液态金属与陶瓷之间的润湿性和结合性，对于制备FRM这样的复合材料是非常重要的。本课题的目的是找出影响陶瓷与液态金属的润湿性和陶瓷与金属之间的结合性的因素，从而制备出复合材料。主要研究结果如下：陶瓷的制备方法对陶瓷与液态金属的润湿性有一定的影响。这一事实表明，通过注意生产方法来控制润湿性是可能的。润湿现象可能会受到陶瓷表面结构的影响。在液态纯铜/碳化硅单晶体系中，观察到了润湿行为的特征。这种行为以前从未被报道过。在该体系中观察到的六方润湿性与SiIA的表面结构有直接关系。本文提出了一种评价液态金属对纤维润湿性的新方法。在铝液中加入一定量的Li，既促进了C的润湿，又抑制了铝液与石墨的反应。

It is very important to know a wetting prorerty and joinability between luquid metal and ceramics to produce a composites materials such as FRM.The purpose to this porject is to clatify the facters which affect a wettabbility of ceramics by liquid metals and a joinability between ceramics and metals and to produce composites materials. The main results were as follows.A production method of ceramics had han an gerat influence on wettabilty of ceramics by liquid metals. This facts suggests that it is possible to control the wettability by paying attention the production method.A wetting phenomenon could be affected by a surface structure of ceramics. In the luquid pure copper/SiC single crystal system, the characteristci wetting behaviout was observed. This behaviour had not been reported before. The hexagonal wetting which was obsavred in the system would have direct relation to a surface structure of SiiA new method for evaluating a wettablity of fiber by luquid metals have been developed.By adding a certain amount of Li to liquid Al, wetting of C was promoted and also the reaction between liquid Al and graphite was restricted.
