摘要

•Oxidation of Cr-coated Zr alloys is studied under steam up to 1500 °C.•Oxidation kinetics vary depending on the actual protectiveness of the Cr coating.•Different underlying diffusion mechanisms are highlighted.•Cr volatilization appears to be negligible.•Effect of Zr-Cr eutectic beyond 1300 °C is studied.
