Si含量为0.25 ~ 3.2wt.%的低Si合金钢的电化学研究IM NaCl硼酸盐缓冲溶液（pH 8.4）中在还原条件下在90°C下进行。硅作为合金元素首先被证明会降低钢的钝化能力。对于较长的浸泡时间，保护效果在含有3.2wt.%硅。钝化层电化学形成的过钝化域上的钢含有3.2%的Si被证明是显着不同的那些生长在静止电位。
Electrochemical investigations on low-Si alloyed steels with Si content ranging from 0.25 to 3.2 wt.% were carried out in a 0.1 M NaCl borate-buffered solution (pH 8.4) in reducing conditions at 90°C. Silicon as an alloying element was proved to degrade at first the steel ability to passivate. For longer immersion times, protective effects developed more efficiently on the steel containing 3.2 wt.% silicon. Passive layers electrochemically formed in the transpassive domain on the steel containing 3.2% Si were shown to be significantly different from those grown at rest potential.
