Abstract

NiCoCrAlY coatings were prepared by EB-PVD on the γ'-based superalloy IC-6. Then the isothermal oxidation test was performed at 1 100°C for 300 h. The element interdiffusion between overlay coating and substrate has been studied with XRD, SEM and EDX. It is found that the remarkable interdiffusion of Cr, Co, Ni and Mo occurs during oxidation at high temperature. However, no brittle phase is formed at the coating/substrate interface.
