Thermal barrier coatings consist of an electron-beam physical-vapor deposited NiCoCrAlY bond coat and 7 wt.% yttria partially stabilized zirconia top coat with a tetragonal phase. The YPSZ top coat shows a columnar grains forming dense clusters with gaps among grain clusters. The roughness of the as-deposited ceramic top coat is relatively low, but some spots of prominent growth defects can be observed. Such defect is a bundle of zirconia columns.
