At an electrode potential of +0.87 V, the electrode surface was rich of acicular Sn and stannum oxide. This film would prevent the electrode from dezincification, and the current density decreased and homeostasis was reached at the same time. The corrosion mechanism of brass welded line in artificial seawater was dissolution/redeposition.

随后，电极表面积累的锡和锡的氧化物及腐蚀产物层对脱锌腐蚀有一定的阻碍作用，电流密度有所下降，最后腐蚀达到一种动态平衡，腐蚀机制为溶解－再沉积机理。

Meanwhile, the coated surface was hydrophobic with a contact angle of 107.2°since the introduction of methyl groups and methylene groups. Static immersing corrosion test, potentiodynamically polarization curve and electrochemical impedance spectroscopy were conducted to evaluate the film corrosion performances. The results of potentiodynamically polarization curve and EIS in 55wt% LiBr solutions at room temperature in atmospherical pressure indicated that the corrosion current density of BMBSE film coated surface was 4 orders of magnitude smaller than that of bare SUS304 steel, and the impedance was increased by a factor of 10000. Static immersing corrosion test presented that the BMBSE film can significantly increase the corrosion resistance in 55wt%LiBr solution at 180°C compared with stainless steels.

同时由于有机组分甲基和亚甲基的引入，结构均匀致密，并具有一定的疏水性；电化学测试结果表明BMBSE膜的极化阻抗比不锈钢大4个数量级，自腐蚀电流密度也下降低了4个数量级左右，具有良好的耐腐蚀性能；成膜的影响因素优化结果表明BMBSE、EtOH、D.I.water摩尔比为1∶4∶3，热处理温度为200℃时，更有利于制备结构均匀、致密、耐腐蚀性能好的薄膜；静态浸泡腐蚀实验结果说明，在180℃、55%的高温溴化锂溶液中BMBSE膜能起到良好的腐蚀防护作用。

The result of SSRT showed that the tensile strength in fusion zone of LBW weldment is higher than base metal, and the IGC in weld decay zone did not crack because of the stretch;IGC in fusion zone of GTAW weldment leads to early fracture, and the IGC in weld decay zone clearly stretched and cause the material to crack. Intergranular stress corrosion cracking in this section is still possible.

慢应变速率拉伸试验结果，LBW焊件之焊道强度高於母材，且於焊接衰化区所造成之沿晶腐蚀并未因拉伸造成开裂；GTAW焊件的焊道沿晶腐蚀导致断裂提早发生，且在焊接衰化区的沿晶腐蚀明显拉伸造成开裂情形，仍有在此区域发生沿晶应力腐蚀破坏的可能。

When subjected to single action of bittern attack or combined actions of bittern attack and wetting-drying cycles, damage of OPC, APC, and HSC are mainly due to chemical corrosions, resulting in several attack products, and also due to crystallization of NaCl-KCl.

在正常温度的单一腐蚀因素和等双因素作用下，OPC、APC和HSC的腐蚀破坏以形成多种腐东南大学博士学位论文蚀产物的化学腐蚀为主，NaCl-KCl物理结晶腐蚀为辅。
