| 摘 要： | 研究了３种不锈钢在衣康酸／氯化钠水溶液中的腐蚀和电化学特性并探讨了介质组成和温度的影响。结果表明，在一定范围内，随衣康酸浓度，氯化钠浓度和温芳的提高，不锈钢的腐蚀速率、致钝电流密度和维钝电流密度也有所增大，不锈钢的点蚀电位与衣康酸介质中Ｃｌ＾－浓度的对数间存在线性关系；

| Abstract: | The corrosion and electrochemical characteristics of three stainless steels in itaconic acid/NaCl aqueous solutions were investigated and effect of composition and temperture of the media was discussed. The results show that the corrosion rate,critical current density for passivation and passive current density of steels increase as the medium's temperature and concentration of itaconic acid and NaCl increase in some ranges.THere is a linear relation between the critical pitting potential of stainless steels and the logarithm of Cl - content in itaconic acid media.The duplex stainless steel R1 has better uniform and pitting corrosion resistance than the austenitic 1Cr18Ni9Ti and 316L. |
