pit corrosion

Study On Pit Corrosion Phenomenon of Flow Passage Blades In No 1 Turbine of Zhan Jiang Power Station

湛江电厂1~汽轮机通流叶片点蚀现象的研究

The anode polarization curve of A0 pure aluminum in DI ( de-ions) water was measured to simulate the pit corrosion of reactor pool shell.

测量A0纯铝在去离子水中的极化曲线用来模拟反应堆池壳的点蚀。

In the limiting current region, an inductance loop appears on the EIS because the breakdown of the oxides film leads to serious pit corrosion.

在极限电流区，腐蚀产物膜产生破损点，导致电极表面快速溶解，产生严重的点蚀，这就是在该区域极化电位下EIS出现感抗弧的原因。

The results have indicated that the main corrosion features of the test alloys are pit corrosion with crevice corrosion in 3 5% NaCl solution;

试验合金在3.5%NaCl溶液中以点蚀为主要特征，伴有缝隙腐蚀；

However, with temperature rise, the saturated brine corrodes the casing steel rapidly in pit corrosion shape mainly.

但随着温度的升高，它对套管钢的腐蚀性急剧增大，腐蚀形态以点蚀为主；在高温条件下，P-110套管钢的耐蚀性优于N-80套管钢。
