论文摘要

我们研究了一氮培养基对不锈钢晶间腐蚀进化的氧化特征的影响。在两个不同的氧化条件(“严重”和“软”)中,钢的腐蚀表面达到了不同的稳态:氧化物厚,晶间凹槽较薄,并且在“严重”条件下的表面积比“软”的条件更大。然后,我们研究了替代性“严重然后软”腐蚀序列的效果。我们表明,该系统重新适应了“软”条件,而没有以前的“严重”的记忆效应。 Bstra

We investigate the impact of the oxidizing character of the nitric medium on the evolution of the intergranular corrosion of a stainless steel. In two different oxidizing conditions ("severe" and "soft"), the corroded surface of the steel reaches a different steady state: the oxide is thicker, the intergranular grooves are thinner and the surface area is larger in the "severe" conditions than in the "soft" ones. Then we investigate the effect of an alternative "severe then soft" corrosion sequence. We show that the system re-adapts to the "soft" conditions without memory effect from the previous "severe" ones. bstra
