摘要
运用红外光谱、拉曼光谱分析的方法,对碳钢A3和低合金钢10CrMoAl经青岛大气腐蚀的锈层样品,进行了比较测试,综合分析得出锈层中主要组成物相为-αFe2O3,-γFeOOH,-αFeOOH,-δFeOOH,Fe3O4,以及各组成物相相对含量随腐蚀时间的变化情况。
In the present study two methods, infrared and Raman spectral analyses, were used to measure the rusty layer of samples with atmospheric corrosion from Qingdao. The main component rust phase of the rusty layer was observed, showing that the relative content of the rust phase varies with the change in corrosion time. The main component rust phases of the rusty layer were found to be α-Fe2O3,γ-FeOOH,α-FeOOH,δ-FeOOH and Fe3 O4, with the relative content of each rust phase of A3 （1） rusty layer sample exhibiting the following relation.γ-FeOOH〉α-FeOOH〉δ-FeOOH, and the relative contents of other rusty layer samples were found to follow the relation.γ-FeOOH〉δ-FeOOH〉α-FeOOH.
