Corrosion Behavior of 316LN Austenitic Stainless Steel in Cl- Containing Solution
-
摘要: 采用慢应变速率拉伸法以及电化学方法，通过与316L奥氏体不锈钢进行对比，研究了316LN奥氏体不锈钢在不同温度（25，50℃）和不同腐蚀介质（质量分数为3%的NaCl溶液、质量分数为6%的FeCl3溶液）中的应力腐蚀开裂和电化学腐蚀行为。结果表明：316LN钢在含Cl-溶液中的应力腐蚀敏感性低于316L钢；316LN钢在NaCl溶液中发生钝化-击穿行为，而在FeCl3溶液中则呈现活性溶解特征，阻抗谱均为单一容抗弧特征，且温度越高，316LN钢的自腐蚀电流越大，容抗弧半径和电荷转移电阻越小。316LN钢的耐腐蚀性能优于316L钢。Abstract: The stress corrosion cracking and corrosion behavior of 316LN austenitic stainless steel were studied by slow strain rate tensile and electrochemical methods in different corrosive media (3wt% NaCl solution, 6wt% FeCl3 solution) at different temperatures (25, 50℃) through comparing with those of 316L austenitic stainless steel. The results show that in Cl- containing solution, the stress corrosion sensitivity of 316LN steel was lower than that of 316L steel. 316LN steel exhibited passivation-breakdown behavior in NaCl solution, while in FeCl3 solution, it presented the characteristics of active dissolution, and the impedance spectrum showed a single capacitive reactance arc in both. The higher the temperature, the larger the self-corrosion current, the smaller the arc radius and the charge transfer resistance of 316LN steel. 316LN steel showed better corrosion resistance than 316L steel.
