## Abstract X‐ray photoelectron spectroscopy (XPS) is used for investigating the valence state of the chemical elements present in 25.5 wt.% CeO~2~βˆ’2.5 Y~2~O~3~βˆ’72 ZrO~2~ plasma‐sprayed coatings as a function of the deposition temperature. Unlike the other chemical elements, cerium changes its vale
