| Abstract Scope |
In this study, the hot corrosion performance of Inconel 939 superalloy was investigated in the mixture of Na2SO4−NaCl at 700 and 800 °C for up to 100h. Results indicated severe hot corrosion attack with increasing the temperature. A duplex microstructure corrosion layer was identified including Cr-depletion zone close to the inner layer. A plausible hot corrosion mechanism as well as the main corrosion products have been proposed based on the results of corrosion tests, XRD and microstructure analysis. Although the corrosion rate at 800 °C is higher than 700 °C, the corrosion products are almost the same at both studied temperatures. |
