| 摘 要： | 以NaCl+NaHSO3为腐蚀介质,通过浸渍干湿复合循环实验及腐蚀失重分析,并利用SEM,XRD和FTIR技术,研究了Q235碳钢和P265GH低合金钢的大气腐蚀行为。结果表明,两种钢的腐蚀遵从相同的动力学规律,腐蚀产物中均存在大量致密的α-FeOOH和非晶态δ-FeOOH,锈层具有很好的保护性,使得腐蚀速率降低。实验开始阶段两种钢的腐蚀量基本相同,但随着腐蚀的进行两者差距增大,P265GH低合金钢较Q235碳钢的失重小、锈层致密、耐腐蚀性好。 |

| Abstract: | The corrosion behavior of P265GH low alloy steel and Q235 carbon steel under dry/humid/immersion alternative condition with NaCl and NaHSO3 were investigated by SEM, XRD, FTIR and mass loss analysis. The results show that, the relationship of mass loss to test time for the two steels fits to the same dynamics law. The corrosion products contain a large amount of dense |
