摘要
采用干湿交替周期浸润腐蚀试验模拟了三种设计的EH36级平台钢在海洋大气环境中的腐蚀行为。结果表明,降低碳含量并且提高铬含量有利于腐蚀锈层致密化,且腐蚀产物主要为对耐蚀性比较有益的α-FeOOH和γ-FeOOH,此类腐蚀产物在腐蚀后期能够明显抑制腐蚀速率的继续增长。
The atmospheric corrosion behaviors of three kinds of EH36 ocean platform steels with different compositions were investigated by cyclic wet-dry corrosion experiments. The results showed that the rust layer tended to be more compact by lowering C content and increasing Cr content. Protective corrosion products goethite (α-FeOOH) and lepidocrocite (γ-FeOOH) were the major constituents of the rust. The corrosion products can inhibit the increase of corrosion rates significantly during the later stage of corrosion.
