摘要
运用多种测试分析方法,对经青岛大气腐蚀后的碳钢A_3、低合金钢10CrMoAl锈层样品进行比较测试,探讨锈层在组织结构方面的特征、锈层外貌以及合金元素赋存情况,分析锈层中各元素的含量、主要组成物相及相对含量随腐蚀时间的变化情况,并对钢的耐蚀行为机制进行研究。
Several methods were used to measure the atmosphere corrosion rusty layer of the carbon steel A3 and low-alloy steel 10CrMoAl samples from Qingdao. The structure, appearance of steel rusty layer, exisence of alloy elements of steel rest body were disscussed. The main component elements and rust phase of the rusty layer were observed, showing that the relative content of the elements and rust phase varied with the change in corrosion time. The mechanism of the anti-corrosion of the steel was put forward.
