研究了耐候钢在青岛近海大气中曝晒3a的腐蚀行为，观察测定了锈层与基体的界面形貌、相组成及锈层中合金元素的分布.结果表明，腐蚀3a的耐候钢表面锈层有明显的分层现象；内锈层组织致密，主要有各向同性的α-FeOOH构成，在偏光下检测消光；外锈层有γ-FeOOH和Fe2O3构成，在偏光下检测炫光；在内锈层中有合金元素的富集

Corrosion rate of carbon steel and the weathering steel in the marine atmosphere by Qingdao for 3 years was compared,and the distribution of the alloy elements in the rust layer was determined.The result shows that the structure of corrosion rust of weathering steel exposed for 3 years consisted of inner layer and outer layer obviously. The former was compacted and composed of αFeOOH mainly,and looked dark by the polarized light. However,the latter is of γ-FeOOH and a little FeO,and appeared bright by the polarized light.
