摘要	PurposeThis study aims to investigate the corrosion resistance and electrochemical dissolution behavior of superalloys treated by different oxidation treatments.Design/methodology/approachNi-based superalloys were subjected to oxidation treatment at 1000 degrees C for 10 h, 1150 degrees C for 10 h and 1200 degrees C for 20 h. The microstructure, electrochemical dissolution behavior, elemental distribution, as well as compactness and composition of the oxide layer, were studied.FindingsThe results show that both the thickness and the granular oxide size of the oxide layer on Ni-based superalloys increase with longer oxidation times and higher temperatures. The electrochemical dissolution efficiency of Ni-based superalloys decreases with increasing oxidation time and temperature. The reduced electrochemical dissolution efficiency observed in Ni-based superalloys oxidation-treated at 1200 degrees C for 20 h is primarily attributed to the thicker oxide layer, which contains the highest Cr oxide content.Originality/valueThe findings contribute to the advancement of recycling and utilization of Ni-based superalloy scrap.
