Using ABAQUS soft by finite element analysis method, the effect of residual stresses distribution by growth of therm ally-growth oxide (TGO) that grows between TGO and bond coat int erface and cone interface topography of bond coat in a TBC system was calculated. The calculating result shows that the residual stress of thermally-growth oxide interface is af fected by interface topography unitsize and topography distribution density obviously. The stress between TGO and top ceramic coating interface is greater than the stress between TGO and bond coat interface. Stress concentrates in topography center and reaches the maximal value. The stress decreases with the increase of topography quantity.
