摘要
通过浸泡法、电化学法研究了EH40 钢在海水模拟溶液中的耐蚀性.浸泡实验结果表明:在1 400h内随着腐蚀时间的推移,试样表面的腐蚀孔洞数量不断增加,在360 h时腐蚀孔洞数量最多,在840 h后表面逐渐有腐蚀产物形成,致使腐蚀孔洞数量增长不明显.电化学测试结果表明:随浸泡时间增加耐蚀性先减弱后增强,360 h时耐蚀性最差.对EH40 钢在模拟海水溶液中的腐蚀行为进行研究具有重要的工程实践意义和理论研究价值,有助于推动海洋工程材料的发展和应用.
Abstract
The corrosion resistance of EH40 steel in simulated seawater solution is studied through immersion and electrochemical methods in this paper.The soaking test results show that within 1 400 hours,as the corrosion time progresses,the number of corrosion pores on the surface of the sample continues to increase.At 360 hours,the number of corrosion pores is the highest,and after 840 hours,corrosion products gradually form on the surface,resulting in an insignificant increase in the number of corrosion pores.The electrochemical test results show that as the soaking time increases,the corrosion resistance first weakens and then enhances,and the corrosion resistance is the worst at 360 hours.The research on the corrosion behavior of EH40 steel in simulated seawater solution has important engineering practice and theoretical research value,which is helpful to promote the development and application of marine engineering materials.
