研究了耐大气腐蚀的低合金钢在不同暴露时间下形成的锈层。结果表明，覆盖在风化低合金钢表面26年的内部稳定保护性锈层主要由含有大量Cr的feooh和Fe1 (Fe1 _X, CrX) OOH （X=0.03）小颗粒组成。锈成分随暴露时间的变化规律支持了新提出的原理图
The rust layers formed on weathering low-alloy steels, which resist atmospheric corrosion, exposed for various periods have been examined. It is elucidated that the inner stable and protective rust layer which covers the surface of a weathering low-alloy steel exposed for 26 years mainly consists of small particles of ƒ¿-FeOOH and ƒ¿(Fe1 _X, CrX) OOH (X=0.03) containing a considerable amount of Cr. The variation in the amount of rust constituents against the exposure period supports well a newly proposed schematic
