| 摘 要： | 腐蚀是钢结构面临的一大耐久性问题,而大气腐蚀是最常见、造成腐蚀损失最大的一类腐蚀.多年来,国内外学者通过在役结构的原位测试、大气暴露试验、室内加速试验、电化学测试等手段对各种钢材的大气腐蚀进程进行了大量研究,对不同环境中的钢材腐蚀机理进行了分析,并提出钢材的腐蚀模型.本文从典型腐蚀性大气环境中建筑结构用钢的腐蚀机理、钢材的腐蚀失重时变模型和钢材表面的蚀坑发展和分布规律等三方面论述了建筑结构用钢的大气腐蚀模型的研究现状和进展.

| Abstract: | Corrosion is a major durability problem for steel structures, and atmospheric corrosion is the most common corrosion that causes the greatest loss. Over the years, researchers have studied the atmospheric corrosion process of various kinds of steel through in-situ test of in-service steel structures, atmospheric exposure test, accelerated corrosion test, electrochemical test, and other methods. The corrosion mechanism of steel in different environments were analyzed and corrosion models were put forward. In this paper, the research status and progress of atmospheric corrosion models of structural steel are discussed from three aspects: corrosion mechanism of steel in typical corrosive atmosphere, time-dependent model of corrosion loss of steel, and pitting depth development and distribution of steel surface. |
