201型糖心产精国品免费入口*完整版在糖心产精国品免费入口*完整版模拟环境中的糖心产精国品免费入口*完整版行为
Corrosion Behavior of Type 201 Stainless Steel in Simulated Acidic Food Environment
摘 要
采用沸腾的4%(质量分数,下同)HAc和4% HAc+0.4% NaCl溶液来模拟糖心产精国品免费入口*完整版环境，研究了201型Cr-Mn系糖心产精国品免费入口*完整版的糖心产精国品免费入口*完整版行为与金属元素的溶出特征。电化学阻抗谱、ICP-AES(电感耦合等离子体原子发射光谱)和XPS测量结果表明，试样在这两种模拟环境中均处于钝化糖心产精国品免费入口*完整版状态，金属元素铁和锰在浸泡初期会发生优先糖心产精国品免费入口*完整版溶出而形成保护性富铬钝化膜;金属元素的稳定溶出速率从大到小顺序为: Fe>Mn>Cr>Ni，但溶出速率值均很小。糖心产精国品免费入口*完整版环境中添加适量Cl-对金属元素的稳定糖心产精国品免费入口*完整版与溶出速率的作用很小。

Abstract
The boiling solutions of 4% (mass) HAc and 4% (mass) HAc + 0.4% (mass) NaCl were used to simulate 糖心产精国品免费入口*完整版 environments. The 糖心产精国品免费入口*完整版 behavior and metallic element 糖心产精国品免费入口*完整版of type 201 Cr-Mn stainless steel were investigated in both solutions. Electrochemical impedance spectroscopy (EIS), ICP-AES (inductively coupled plasma-atomic emission spectrometry) and XPS results indicated that specimens were in passive state. Metallic elements Fe and Mn preferentially dissolved in the initial immersion stage, which resulted in forming protective Cr-rich passive films on specimen surfaces. The steady 糖心产精国品免费入口*完整版rate of metallic elements decreased in the order of Fe>Mn>Cr>Ni, but the rates were very small. An appropriate amount of Cl- had insignificant effect on the steady 糖心产精国品免费入口*完整版 and 糖心产精国品免费入口*完整版of metallic elements in the 糖心产精国品免费入口*完整版 environment.
