【摘要】 研究了３Ｃ（Ｗ ）、１６Ｍｎ、９２１ 三种钢在南海榆林海域全浸、潮差、飞溅环境中暴露８ 年的腐蚀行为。其中，９２１ 钢在飞溅区具有优良的耐蚀性，而在全浸和潮差区耐蚀性不如３Ｃ（Ｗ）钢和１６Ｍｎ 钢的。发现９２１ 钢在全浸区暴露２ 年后发生腐蚀率随时间增加而增大的“逆转”现象。更多还原

【Abstract】 The corrosion behaviors of 3C(W), 16Mn and 921 steels are studied in the all submerged area, tide area and splash area in the Nanhai Sea Yulin water for 8 years. It is revealed that in the splash area the corrosion resistance of 921 steel is more excellent than that of 3C(W) and 16Mn steels, while worse in the all submerged area and splash area. In the all submerged area, the corrosion rate of 921 steel decreases in the first two years and then increases with the time going on.更多还原
