A computer-aided interactive system for coating design has been developed, which enables to conveniently analyze the reaction diffusion of bonded materials including coating components and composites etc. this system consists of an interactive preprocessor, a reactive diffusion analysis based on a parabolic time law and a postprocessor of calculated results. The analysis can be easily conducted by the selection of menus and the data input acceding to a few commandsThe reaction diffusion of interface between the plasma sprayed CoCrAlY and the single crystal substrate of CMSX-2 are analyzed using the developed system. It is clear that the diffusion distance during heating process can not be ignored in comparison with the total diffusion distance. As a result, it is confirmed that the developed system is useful to apply for designing the coating system for gas turbine.
