论文简介 | Abstract The intrinsic deformation accompanying the growth of thermally grown oxide (TGO) can induce significant local stress potentially causing interfacial delamination and coatings fracture in a thermal barrier coating system (TBCs). Multiple mechanisms can be involved in a TGO growth process which is sensitive to the reactive elements contained in the coatings, and as a result anisotropic and nonuniform growth deformation can be produced in the TGO layer. The objective of this study is to analytically and numerically investigate the oxide- ... |
