摘要: 采用模拟浸泡实验、腐蚀形貌分析以及动电位极化和电化学阻抗技术研究了X52和X80钢在模拟海水环境中的腐蚀行为。结果表明:饱和氧时即模拟浅海条件下,X80和X52钢试样表面全面腐蚀和点蚀都会发生,腐蚀速率较大;低氧时即模拟深海条件下,二者主要发生点蚀,腐蚀速率较小。通过对X52和X80钢在模拟海水环境中针对含氧量这一影响因素的腐蚀行为与规律的对比分析得出,X80钢更适用于深海。

Abstract:The corrosion behavior of X52 and X80 steels in simulated seawater environments was investigated by immersion test, electrochemical impedance spectrums (EIS) measurement and surface examination by scanning electron microscope (SEM). It was demonstrated that when the solution was not deoxidized, which was the simulation of shallow sea environment, both of general corrosion and pitting corrosion would occur on the surface of X52 and X80 steels, the corrosion rate was relatively high; when the solution was deoxidized, which was the simulation of deep sea environment, there was mainly pitting corrosion occurred on the surface of X52 and X80 steels, the corrosion rate was slow. By comparison the corrosion behavior of X52 steel and X80 steel in the simulated seawaters in which oxygen concentration was mainly considered, it is clear that X80 steel is more suitable for deep sea environment.
