AbstractNi + CrAlYSIN nanocomposite coatings and NiCrAlYSi coatings were prepared on a nickel-based superalboy K417 by vacuum arc evaporation. Both coatings exhibited excellent cyclic oxidation resistance at 1000 degrees C for 200 1-h cycles. Cracking/spallation of thermally grown oxide (TGO) scale occurred only on NiCrAlYSi coatings, due to the lower thermal stresses level in the TGO on Ni + CrAlYSIN coatings. An hcp-AlN interlayer eliminated the interdiffusion between the nanocomposite coating and substrate. The thickness of the TGO scale on NiCrAlYSi coatings was twice that of the scale on the AlN/Ni + CrAlYSiN coatings, probably due to the crack and healing effect. (C) 2013 Elsevier Ltd.
