摘要
研究了X80管线钢在西南土壤中的腐蚀行为。结果表明,随着腐蚀时间的延长,X80钢的腐蚀速率缓慢增加,腐蚀过程趋于以氧扩散过程控制。腐蚀50 d后表面形成致密锈层,可起到保护作用。
The corrosion behavior of the pipeline steel X80 in Southwest soil environment was investigated. The results show that the corrosion rate of the steel X80 increases slowly with the prolongation of the corrosion time, and the corrosion course tends to be controlled by the oxygen diffusion process. The dense rust layer is formed on the surface of the steel X80 after corrosion for 50 days, which can play a role of protection.
