Abstract | Cyclic hot corrosion tests have been carried out on three coatings (one NiCoCrAlY and two composite coatings) at 700 and 900 degrees C. The kinetic curves and evolution of microstructure show that the composite coating with a Cr-base interlayer performs best. The Cr2O3 scale is more effective to protect the coating at 700 degrees C than that at 900 degrees C. The corrosion process is accelerated by NaCl via forming volatile MClx and inducing the formation of molten voids in the coating or extra oxidation at the interface of fusant/oxide scale, determined by the temperature and the compositions of the coating.
