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- ...
