设计并建立了实验室模拟流动海水腐蚀试验装置。对A3、20#、X70钢挂片和20#钢管路在流动人工海水中全浸暴露2、4、8、16、32天的腐蚀行为进行了试验研究。试验结果表明,流动海水中碳钢的腐蚀速率先降后升,然后趋于稳定;在动水试验中,锈层分为两层,底层以Fe3O4为主,表层以Fe2O3为主;在静水试验中,锈层以Fe2O3为主。
A simulated flowing seawater corrosion test system was set up,the corrosion behaviors of carbon steels in simulated seawater were studied using the system.The weight loss tests of A3,20# and X70 steels were conducted to show the corrosion rate data in static and flowing seawater for comparison.Results showed that the corrosion of A3,20# and X70 steels was accelerated in the flowing seawater due to the erosion-corrosion effect on the surfaces of metal materials.The corrosion rate showed a decrease first and then an increase,and gradually became stable later.The rust layers were divided significantly into two layers in the flowing water experiment.
