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

• The nanoscale TiO 2 layer was covered by anatase and ilmenite crystallites. thin evolution modelled a Loriers-Haycock model. Titanium precipitation ratii were defined measured. A phenomenological model proposed to link mass variation corrosion rate. Corrosion rates of all studied materials stand between 6.6 μm/year at 300 °C. titanium alloys in primary water °C led global weight gain due oxidation surface precipitation, despite some dissolution. proposed, taking into account the contribution each oxide type with exposure time. Based on this model, GD-OES results, rate ranging μm.year -1 for tested estimated. Due simultaneous used stainless steel reactors, protective finally precipitated samples.
