摘 要:The ceramic/metal gradient thermal barrier coatings (CMGTBCs) which combined the conceptions of thermal barrier coatings (TBCs) and functional gradient materials (FGMs) are *** structure model studied in this paper is a general model which includes four different layers:pure ceramic layer,ceramic/metal gradient layer,pure metal layer,and substrate *** microstructures of gradient layer have different ceramics and metal volume fraction profile along with the direction of *** profile function used to describe the gradient microstructures can be expressed in power-law or polynomial *** mechanical properties of CMGTBCs are obtained by means of microscopic *** special cases,the interactive solutions are given by Mori-Tanaka method,and the non-interactive solutions by dilute *** Young s modulus calculated by these methods are compared with those by other methods,e g,the rule of mixtures.
