摘要
测量了碳钢与耐候钢在海南地区大气中的腐蚀速率 ,分析了锈层的组成及合金元素的分布。结果表明 ,腐蚀 2年的碳钢锈层是疏松多孔的块状锈层 ;耐候钢锈层是较致密的片状锈层 ,内锈层主要由α FeOOH组成。疏松锈层含有S ,致密锈层含有Cr。
Corrosion of carbon steel and weathering steel exposed for 2 years in Hainan was compared and the distribution of deferent components and alloy elements in the rust layer was determined. The results show that the structure of rust formed on weathering steel is sheety layer containing Cr, while the structure of rust of carbon steel is lump containing S. The function of Cr and S in the rust layers is analyzed.
