【摘要】 本文旨在寻求一种结构控制手段，实现梯度材料在组成成份上连续分布。从颗粒共沉降的立场出发，建立了Ａ／Ｂ 系ＦＧＭ 沉降模型，并从理论上对用共沉降法制备Ａ／Ｂ 系ＦＧＭ 时，材料内部可能出现的界面情况进行了分析，提出了解决方案，为用共沉降法制备组成成份连续或准连续分布的ＦＧＭ 提供理论依据。更多还原

【Abstract】 This article is seeking for a way to control the material structures in order to make the compositions of FGM (Functionally Graded Material) continuously distributive.From the viewpoint of the sedimentation,we have set up the deposition model of A/B system FGM and analyzed the possible interfaces of FGM in theory,and have also given corresponding solutions.The article has laid a foundation for FGM with continuous or quasi-continuous compositions by sedimentation.更多还原
