The background of this project is the salt erosion and heat erosion in the ceramic thermal barrier coating (YSZ) on blade of gas turbine and jet engine at high temperature. In the project, the mechanism of salt reaction thermodynamics and kinetics in the TBCs will be studied and to find an effective additives for anti-erosion, through a specially designed experimental instrument simulating the spot condition of turbine operation. At the same time, select the multi-additives for anti-thermal erosion and phase transition at high temperature by theory analysis and model simulation. Study on the effects of content, composition of additives on the structure and properties of TBC；the kinetics of high temperature erosion and phase transition and mechanism, to find the mechanism for stabilization of additives in the TBCs. Built the mathematical and physical model of anti-erosion and phase stabilization on multi-additives for zirconia base TBCS. Acquire theory and method for the heat anti-salt erosion and thermal erosion and phase transition of TBCs.
