Corrosion of titanium alloys in pressurised water at 300 °C: Kinetics and modelling

•The nanoscale TiO2 layer was covered by anatase and ilmenite crystallites.•The thin TiO2 layer evolution was modelled by a Loriers-Haycock model.•Titanium and ilmenite precipitation ratii were defined and measured.•A phenomenological model was proposed to link mass variation to corrosion rate.•Corrosion rates of all studied materials stand between 2 and 6.6 μm/year at 300 °C.
