Abstract

Microtextures of the thermally grown α-alumina (TGO) in isothermally treated and thermal cycled electron beam physical vapor deposited thermal barrier coatings (EB-PVD-TBC) and isothermally treated air plasma sprayed (APS-TBC) specimens were studied by high resolution electron back-scattered diffraction. The TGO in EB-PVD specimens exhibited a basal microtexture. The TGO in APS specimens, however, did not show any significant microtexture development.
