表面处理技术在梯度功能材料制备中的应用

Application of Surface Technologies to the Preparation of Functionally Gradient Materials

介绍梯度功能材料（ＦＧＭ）的制备方法和应用现状，详细介绍了气相沉积法、等离子喷涂法、激光熔覆法、电化学法等几种表面处理技术制备ＦＧＭ的基本原理及实例，并指出了ＦＧＭ发展中存在的问题和方向。

The current situation of functionally gradient materials (FGM) is rev iewed including their fabrication and application. Surface technologies of prep aring FGM such as vapor deposition method,plasma spraying method, laser cladd ing method and electro chemistry method are introduced. The prospects and que stions of FGM in development are discussed in this paper,too.
