| Popis: | The corrosion of titanium alloys in primary water at 300 °C led to a global weight gain due to oxidation and surface precipitation, despite some dissolution. A model was proposed, taking into account the weight contribution of each oxide type to the global mass evolution with exposure time. Based on this model, on mass variation and GD-OES results, a corrosion rate ranging between 2 and 6.6 μm.year-1 at 300 °C for all tested materials was estimated. Due to the simultaneous corrosion of the used stainless steel reactors, a protective ilmenite layer finally precipitated at the surface of the samples. |
