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。

In near-neutral pH solution, the cracking mode is transgranular with the feature of quasicleavage.The function of SCC factors are as follows:(1)The additional potential takes an important role in the SCC behavior of X70 pipeline steel: the susceptibility to SCC increased with decreasing cathodal potential,HIC is the dominant reason,the crackles on the surface are almost vertical to stress;On the country, at anodic potential,there is a critical potential,below which the dominant reason is anode-dissolving supported by hydrogen,and the crackles on the surface are not vertical to stress.

电位因素和环境因素的影响作用为：(1)在阴极极化电位区，SCC敏感性随电位的负移而增加，氢致开裂作用占主导，表面裂纹多与拉应力垂直；在阳极极化区间，存在阈值电位，低于阈值电位时，SCC为氢促进阳极溶解所致，表面裂纹多与主应力方向成一定角度。

The batch seeded isothermal desupersaturation experiments of SPM in aqueous solution were carried out and the overall crystal growth kinetics parameters were determined by the nonlinear optimization techniques. Assuming that the volume diffusion rate at growth is equal to the mass transfer rate at dissolution under the same conditions, the two-step crystal growth rate parameters can be determined. At the fow supersaturation, the surface integration rate is proportional to relative surface supersaturation.
