| 摘 要： | 应用电化学稳态技术、电化交流阻、抗微区电化学技术及扫描电等方法，研究１８／８型不锈钢在Ｎａ２Ｓ２Ｏ３稀溶液中，受外力形变条件下，的腐蚀电化学行为，结果表明，力学因素可使表面腐蚀电化学活性增加，表面微裂纹的发生、消失和再钝化的动态过程，同时受电位和拉应力的影响；点腐蚀可优先发生在应力集中位置，点蚀的发展可能诱导不锈钢的应力腐蚀开裂。

| Abstract: | The electrochemical behavior of l8/8 stainless steel in dilute thiosulphate solutionduring strained loading was studied by various electrochemical techniques and scanning electronmicroscope.It is evidenced that the corrosion activity of stainless steel increased with strained loading.The dynamic process of repassivation ,which may datermine the initiation ,the cease and developmentof the stress corrosion cracking for stainless steel ,was strongly influenced by both electrochemical andloading conditions. Pitting corrosion may locate preferentially on the sites which was suffered mostloading.The propagation of pitting corrosion of stainless steel may induce stress corrosion crakingunder certain conditions. |
