Effect of Al plating on growth behavior of TGO layer in CoCrNiAlY–YSZ–RSZ dual-ceramic coating

Thermally grown oxides (TGO) are the key to determine the longevity of thermal barrier coatings (TBCs). This study investigates the growth behavior of the TGO layer in a dual-ceramic coating consisting of CoCrNiAlY, yttria-stabilized zirconia, and rare earth-stabilized zirconia (CoCrNiAlY–YSZ–RSZ) w...
