梯度功能材料的优化设计及发展

梯度功能材料是 2 0世纪 80年代出现的一种新型功能材料 ,具有许多优良性能 ,因此 ,得到广泛应用。该文论述了梯度功能材料的优化设计与制备方法 ,其设计思想是通过 2种或 2种以上性质不同的材料 ,连续改变其组成、组织、结构与空隙等要素 ,使其内部界面消失 ,得到可应用于高温环境下新型功能材料。目前 ,该材料的发展已突破耐高温材料的领域 ,并向能源、化工、光学、电学及生物医学工程等领域发展与应用

Optimum design and development of functionally gradient materi als

The new functional materials, which appeared in the 1980's,have been widely used for many good properties.The optimum design and manufacture methods of functionally gradient materials have been discussed in the paper.According to the design idea of functionally gradient materials,two or more than two kinds of materials having different properties are chosen,and their properties such as composition,organization,structure and hollow are changed continually so as to destroy the interface and obtain a new functional material which can be applied in the environment of high temperature. The development of the new materials has broken through the field of high-temperature-resistant materials, and the new materials have been applied to many other fields such as sources of energy,chemical engineering,optics, electricity,biology and medical engineering.
