| 中文摘要: |
| 介绍了海洋腐蚀环境的特点，分析了钢结构焊接接头的腐蚀特性。在此基础上，总结了国内外学者关于焊接接头在海洋环境下的腐蚀机制和影响因素等研究成果，明确了焊接接头以电偶腐蚀、应力腐蚀和腐蚀疲劳为主导的电化学腐蚀行为。针对钢结构焊接接头的海洋腐蚀防护要求，总结了当前主要的腐蚀防护方案，如添加合金元素、焊接工艺优化、热处理、表面强化和防腐涂层等。最后，综合当前钢结构焊接接头海洋腐蚀与防护研究现状，提出了在海洋实际工况验证和防护手段不足等方面的问题。 |
| 英文摘要: |
| In this work, the characteristics of marine corrosion environment were introduced and the corrosion characteristics of welded joints of steel structures were analyzed. On this basis, the research achievements of domestic and foreign scholars on the corrosion mechanism and influencing factors of welded joints in the marine environment were summarized, and the electrochemical corrosion behavior of welded joints dominated by galvanic corrosion, stress corrosion and corrosion fatigue was defined. According to the requirements of marine corrosion prevention for welded joints of steel structures, the main corrosion prevention schemes were summarized, such as adding alloy elements, welding process optimization, heat treatment, surface strengthening and anti-corrosion coating. Finally, based on the current research status of marine corrosion and protection of welded joints of steel structures, the problems of insufficient verification in actual marine working conditions and inadequate protection measures were proposed. |
