摘要：
The microstructure and corrosion behavior was studied for a Co modified NiAl coating formed on the superalloy DZ125 by pack cementation process. The hot corrosion kinetics showed that the mass gain of the coated specimen was three orders of magnitude lower than that of the uncoated specimen at 1173 K up to 100 h. The corrosion product formed on the surface of the coating mainly consisted of a protective alpha-Al2O3 film. The presence of Co in the coating could promote the establishment of a protective Al2O3 scale on the coating and restrain the internal diffusion of sulphur in the coating. (C) 2012 Elsevier Ltd.
