Microstructural and high-temperature cyclic oxidation response of NiCoCrAlY coatings with and without SiC + ZrB2 reactive-element dispenser
•The SiC-ZrB2 can be used as a reactive-element (Si) compound dispenser.•Silicon behaves as a reactive-element reducing the oxidation.•Coatings with 1 % SiC-ZrB2 displayed thinner TGO layers and a lower oxidation rate.•Silicon seems to promote the stabilization of α-Al2O3 at earlier stages of oxidat...
