Study on the corrosion behavior of EH40 steel in simulated seawater solution
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.
