中文摘要:
      概述了作为铝网壳结构的AA 3xxx铝-锰合金微观组织、局部腐蚀类型及表面防护技术。同时归纳了主要的表面处理方法,包括“硬质阳极氧化膜+封闭工艺”、“化学转化膜+涂料工艺”和添加缓蚀剂等,并重点评述了“化学转化膜和涂料工艺”。其中,六价铬转化膜是应用于铝合金表面最传统也是最成功的化学转化膜,但六价铬剧毒致癌,因而该技术已经被禁止应用于工业产品,具有自修复腐蚀缺陷功能的三价铬转化膜工艺是最具前景的替代工艺。目前,商业化的三价铬转化膜溶液包括汉高Alodine 5900系列、赛德克SurTec 650系列以及法国索科SOCOMORE溶液,而国内相关基础研究起步较晚,性能相匹配的国产化溶液及工艺控制成为未来轻量化装备发展的“卡脖子”问题,亟待解决。此外,着重讨论了化学转化膜溶液组分、工艺参数(温度、时间及后处理工艺)及耐蚀性能等。最后总结和展望了三价铬铬酸盐转化膜现在和未来的研究思路。
英文摘要:
      The present work summarized microstructure, types of localized corrosion and surface protection technologies of AA 3xxx Al-Mn alloys, being the main materials for the latticed shell structure. In addition, the main surface treatment methodologies are introduced and included the “hard anodizing oxide film + closure process”, “chemical conversion coatings + painting process” and inhibitor addition. Notably, “chemical conversion coatings + painting process” is importantly reviewed. Chromate conversion coatings, being the conventional process applied on aluminium and its alloys, are the most effective and successful. However, the high toxicity of carcinogenic chromate species limited the industry application. The trivalent chromium conversion coatings are regarded as the most promising alternatives of next-generation surface treatment due to the self-healing property and high corrosion resistance performance. The commercial trivalent chromium conversion coating solutions contain the Henkel Alodine 5900, SurTec 650 and France SOCOMORE solutions. In comparison, the research basic is weak and slow progress of homemade solutions highly limited the future of light-weight equipment. This “bottlenecks” problem necessitates the research solutions. This paper emphatically discussed solution components, process parameters (temperature, time and post- treatment process) and corrosion resistance of chemical conversion coatings. Finally, the present research and future development of trivalent chromium conversion coating are summarized and prospected.
