Abstract A study of morphology of simple oxidation and hot corrosion of the aligned Co-10 wt.% Cr-14 wt.% TaC alloy was performed at 900°C in still air. The morphology of simple oxidation was found to correlate well with previous results on similar alloys. Hot corrosion tests were performed by coating the samples with a thin layer of Na2SO4 and exposing them to still air at 900°C. A radically different morphology was found and extensively analyzed using optical microscopy and the electron microprobe. These results are then explained using a localized reduction model of hot corrosion.
