Abstract
Density functional theory (DFT) and autoclave corrosion tests in 360 °C water were used to investigate the influence of Sb, Sc, Nb and Sn on the corrosion and hydrogen pick-up (HPU) of Zr-alloys. Sc was shown to have a strongly detrimental effect on alloy corrosion resistance. The Nb–Sb–Zr ternary alloy exhibited significantly improved corrosion resistance over Zr–Nb and ZIRLO, and had little measurable HPU after 195 days. The ratio of View the MathML source was shown to transition smoothly with applied space charge, implying Sb can act as a buffer to charge imbalance in the oxide layer.
