The evaluation of oxide scale formation during hot corrosion of Rene-80 superalloy under thermal shock at different dwell times

In this study, the oxide scale formation on the Rene-80 superalloy after hot corrosion under thermal shock has been investigated. The X-ray diffraction (XRD) and field-emission scanning electron microscope (FE-SEM) were used for the phase identification and evaluation of oxide scale, respectively. The hot corrosion test under thermal shock was performed by depositing Na2SO4 salt at the beginning of each cycle on the surface of the specimens. The...
