性能渐变材料原理及其应用于耐火材料的技术可能性

The principle of FGM and its possibility applied to refractories

性能渐变材料（ＦＧＭ）是其组成（成分）从一个面到另一个面呈阶梯变化或连续变化，而其性能也随之渐逐变化的非均质复合材料。本文概述了ＦＧＭ的概念及其各种制备技术和技术关键；初步探讨了将ＦＧＭ原理应用于耐火材料的技术可能性；提出了开发性能渐变耐火材料（ＦＧＲ）的设想和值得注意的问题。

The functionally gradient material(FGM)is a non-homogeneous composites which feature a gradual change in properties with the gradient or continuous change of component from one surface to the other.In the poper,the concept of FGM,various preparing technology and technical key are introduced.The technical posibility of the FGM principle applied to refractories is discussed.And tentative ideas as well as the problem worthy of note in developing functionally gradient refractories(FGR)are put forward.
