The corrosion of metallic alloys underneath fused salt films (“hot corrosion”) is an important degradation problem.  Chromium is a key alloying element in defending against hot corrosion because of its ability to form a protective adherent oxide layer. The role of chromium in the hot corrosion resistance of binary nickel-chromium alloys exposed to molten sodium sulfate was studied by systematically varying the chromium content of the alloys. Alloy samples were immersed in the molten salt for different times at 900C and weight loss data were obtained. These results were compared with those obtained from coating samples with a thin salt film and subsequently exposing them to air at high temperatures.  Microstructural analysis of the corrosion front  and the kinetics of the corrosion process obtained by both techniques will be reported.  The current status of electrochemical tests will be presented as well.
