Abstract

Highlights: [•] Dy/Hf-doped β-NiAl coatings are produced by electron beam physical vapor deposition. [•] Cyclic oxidation behavior of the Dy/Hf-doped coatings is compared. [•] The microstructure of scales and chemistry of scale/coating interfaces are studied. [•] Dy and Hf may directly improve the adhesion of the scale/coating interfaces. [Copyright &y& Elsevier]
