The Research of Coat Materials Performance Based on Multi-Scale Method
As for the multi-scale coupling phenomenon among substrate, bonding coat and coating in thermal barrier coating materials, the method of wavelet-based homogenization are used to convert the thermal equilibrium equation into a group of algebraic equations. Using this method, an operational matrix of integration based on the wavelet is established and the procedure for applying the matrix to solve the temperature and displacement are formulated. The results provide a theoretical basic for selecting coating thickness of thermal barrier coating materials in optimization design.
