Abstract :
NiCoCrAlY bond coat was deposited on Ni-based superalloy by means of EB-PVD method. Surface treatment by means of polishing and shot-peening methods were used in order to study the effect of surface conditions on the bond coat performance at 1100 °C. Oxidation resistance was found to be strongly affected by surface modification during pre-oxidation treatment.
