Abstract

The cyclic hot corrosion behavior of cobalt based DZ40M and nickel based K452 superalloys beneath molten deposit NaCl in air at 900 ℃ was studied by means of gravimetric method, XRD, SEM, EDS, scratch instrument and two-dimensional profilometer. The results of 15 cycle testing revealed that K452 is superior to DZ40M in corrosion resistance, which may be ascribed to the higher content of Al, Ti and Ni of K452 alloy. In other word, the formed external scale of NiTiO₃ on K452 alloy can effectively prevent molten salt corrosion, while the inner scale of Al₂O₃ ensures the close bonding between the corrosion product scale and the matrix.

Key words: DZ40M K452 NaCl molten salt cyclic hot corrosion
