ABSTRACT The corrosion performances of the EH 36 carbon steel in stagnant and flowing natural sea water and synthetic sea waters were investigated. Results show that the general corrosion rates of the steels are close in stagnant natural sea water and synthetic sea waters. The corrosion rate, corrosion feature and the rust components of the steels in flowing 3.5% NaCl solution were significantly different from those of the steels in flowing natural sea water, indicating 3.5% NaCl solution could not restore the flow accelerated corrosion (FAC) performance of carbon steels in marine environment. The pH difference between 3.5% NaCl solution and natural sea water is not the main contributor for FAC performance changing. The corrosion performance of the steel in ASTM D1141 synthetic sea water was similar to that in natural sea water within small deviations of the corrosion rate at both static and flowing conditions.

探索碳钢在流动天然海水和合成海水中的腐蚀性能

摘要 研究了 EH 36 碳钢在停滞和流动的天然海水和合成海水中的腐蚀性能。结果表明，在停滞的天然海水和合成海水中，钢的一般腐蚀速率接近。钢在流动的 3.5% NaCl 溶液中的腐蚀速率、腐蚀特征和锈蚀成分与流动的天然海水中的钢有显着差异，表明 3.5% NaCl 溶液不能恢复钢的流动加速腐蚀（FAC）性能。海洋环境中的碳钢。3.5% NaCl 溶液和天然海水之间的 pH 值差异不是 FAC 性能变化的主要因素。
