[交流] 求助:翻译摘要

摘要:以原子比为3﹕1的Fe粉和Si粉球磨20 h后加入一定量的Cu,在(1000±30)℃,20 MPa的压力下通过热压烧结的方法制备了致密的Fe3Si-Cu复合材料。通过浸泡腐蚀和电化学腐蚀两种方法讨论了加入不同质量分数Cu(5%,10%)的Fe3Si-Cu复合材料在NaOH溶液中的腐蚀行为。结果表明,加入5%Cu的复合材料具有更好的耐腐蚀性能。Fe3Si-5%Cu的浸泡腐蚀速率要小,腐蚀的要轻一些;Fe3Si-5%Cu 和Fe3Si-10%Cu两种材料在不同摩尔浓度的NaOH溶液中的极化曲线都出现了钝化,有宽泛的钝化区域,明显的钝化平台,两种材料在不同摩尔浓度的NaOH溶液中的腐蚀是一种均匀的全面腐蚀,没有出现点蚀现象。比较极化曲线的特征值,Fe3Si-5%Cu在0.7 mol/l的NaOH溶液中的自腐蚀电位更正,自腐蚀电流小,并且最先进入钝化区,在钝化区域,维钝电流也小。

With a Fe to S atomic ratio of 3, the mixture of the powders was ball ground for 20 h before adding a certain amount of Cu. Then dense Fe3Si-Cu composite material was prepared by hot-pressing of the resultant mixture under 20 MPa and (1000±30)℃.

abstract:
With an atomic ratio of  Fe/S=3,the mixture of the powders was ball milled for 20 h before adding some Cu.We have prepared dense Fe3Si-Cu composite material by the method of Hot-pressing Sinter-roasting under 20 MPa and (1000±30)℃.Also we discussed the corrosion behavior  of Fe3Si-Cu composite material with different concentrations of Cu(5%,10%)in NaOH solution by two methods of static immersing corrosion and electrochemical corrosion.It turned out that the composite material with 5%Cu had better
corrosion resistant.The speed of static immersing corrosion of Fe3Si-5%Cu was less,the extent of corrosion was also less.The polarization curves of
Fe3Si-5%Cu and Fe3Si-10%Cu composite material appeared passivation in different molar concentrations of NaOH solution,and there was a broad area of
passivation and apparently inactive platform.The corrosion of the two kinds of composite material was evenly rounded corrosion in different molar
concentrations of NaOH solution.There was no pitting phenomenon appearing.Compared with characteristic values of the polarization curves,corrosion potential of Fe3Si-5%Cu revised in 0.7 mol/l of NaOH solution,its electric current of corrosion potential is small,and it went to area of passivation first .In area of
passivation,maintaining passivity current was also small.
