A_3碳钢和10CrNiCuP低合金钢大气腐蚀锈层的研究

Research on the Rusty Layers of A_3 Carbon Steel and 10CrNiCuP Low-alloy Steel Rusted in Atmospheric Condition

运用多种测试分析方法,对经成都大气腐蚀的A3碳钢和10CrNiCuP低合金钢锈层进行研究,对锈层物相组成、锈层阻抗、合金元素赋存情况以及锈层中各元素含量的变化情况进行了分析,讨论了A3碳钢和10CrNiCuP低合金钢的耐腐蚀机制。

In this paper, the rusty layer samples of the As carbon steel and 10CrNiCuP low-alloy steel which were placed in Chengdou air condition were investigated busing several methods.The phase variety,the impedance of rusty layers and the alloying elements existed in the layers were analyzed.The anti-corrosion mech- anism of the A3 carbon steel and 10CrNiCuP low-alloy steel was also discussed.
