When Ts is 850 ℃,grains are fined and the size of βphase and the distance betweenβphase pasticles are small.The corrosion barrier effect ofβ phase onαphase is enhanced and the iron content does not increase much at this temperature.So the corrosion resistance is improved.The corrosion resistance of AZ70 alloy falls off when Ts is 890 ℃,which attributes to the presence of microporosity,hot cracking and increase of iron content.
过热温度为810 ℃时,热速处理对合金耐腐蚀性能的改善作用并不大;过热温度为850 ℃时,热速处理显著细化了合金晶粒,β相的尺寸和间距变小,β相对α相腐蚀的阻碍作用增加,而且合金中的铁含量并没有提高,从而改善了合金在试验条件下的耐腐蚀性能;过热温度为890 ℃时,组织中存在热裂纹和显微疏松缺陷,合金含铁量显著增高,合金的耐腐蚀性能下降。

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。
