Abstract The sulfide NaCrS2 has been identified in the internal corrosion zone of several nickel-base superalloys under basic fluxing conditions at very negative potentials in a 90% Na2SO4-10% K2SO4 melt at 1173 K. It can also be formed in the presence of carbon-contaminated sulfate. NaCrS2 can dissolve some Ti, Al, Ni, and Co; other elements, e.g., K, Mo, W, Nb, Ta, and Zr, could not be detected.
