英文摘要	通过自行设计的深海环境模拟装置，采用静态挂片失重、动电位极化曲线及电化学阻抗谱（EIS）等方法系统研究了深海静水压力环境下低合金高强度钢（HSLA钢）在3.5% NaCl溶液中的腐蚀行为，并与常压下的结果对比，探讨了静水压力下HSLA钢在深海环境中的腐蚀行为. 结果显示，静水压力并没有改变HSLA钢在3.5% NaCl溶液中的腐蚀历程，不甚影响其阴极过程，而主要提高了其阳极腐蚀速率，这可能与高静水压下Cl-活性的增加有关.; The corrosion behavior of a high strength low alloy steel (HSLA steel) in 3.5% NaCl solution under hydrostatic pressure (HP) in deep ocean has been investigated by performing weight loss measurement, obtaining potentiodynamic polarization curve and emplying electrochemical impedance spectroscopy (EIS) using the set up for simulation of deep sea environment in laboratory. The results were compared with that at atmospheric pressure and the influence of HP was emphatically discussed. The results revealed identical corrosion mechanism for HSLA steel at 3.5 × 106 Pa and 1 × 105 Pa. Howevere, the development of such a corrosion process was remarkably accelerated at HP. In addition, the cathodic process of HSLA steel was little influenced at HP, while the anodic dissolution process became faster partly attributed to the enhanced activity of Cl- ions.; 国家自然科学基金项目（No.51271187）资助; 作者联系地址：中国科学院金属研究所金属腐蚀与防护国家重点实验室，沈阳 110016; Author's Address: State Key Laboratory for Corrosion and Protection, Institute of Metal Research, Chinese Academy of Sciences, Shenyang 110016, China; 通讯作者E-mail：liying@imr.ac.cn
