Dy-Co-modified aluminide coating was deposited onto Ni-based superalloy DZ125 using pack cementation method. The microstructure and hot corrosion behavior of the coating were investigated. The results show that as-deposited coating has a two-layer structure. The outer layer of the coating is composed mainly of Al0.9Ni1.1with dispersed Dy2Hf2O7. The mass gain of the coating is 0.23 mg/cm2after exposure to 75 wt.% Na2SO4+ 25 wt.% NaCl at 900 °C for 100 h. The corrosion product formed on the coating is characterized as Al2O3. Role of Dy in the improvement of the hot corrosion resistance has been discussed.
