摘要	Two Ni-Co-Cr-Al-Si-Y (M14 and M19) coatings with different Al and Cr contents were deposited onto DD32 Ni-base superalloy substrate using arc ion plating (AIP) method. The microstructures, isothermal oxidation behaviors at 1000 and 1100 degrees C and cyclic oxidation behaviors between room temperature and 1000 degrees C of the both coatings were investigated. The results show that these two coatings are composed of gamma'/gamma, beta-NiAl and some alpha-Cr precipitate phases. The only difference is that there are more beta-NiAl phase precipitates in M19 coating with high Al content. M19 coating, in contrast to M14 coating, can not only repair destroyed alumina scales effectively during isothermal oxidation, but also resist further cracking and spalling of alumina scales during cyclic oxidation. High Al content in M19 coating can be kept under long time oxidation, making M19 coating long-term service.
