| 目的 研究湿热海洋、湿热雨林、暖湿酸雨典型气候环境对7A04和2A97铝合金性能的影响。方法 通过对7A04和2A97铝合金试样进行户外暴露试验，结合外观形貌观察、力学性能检测、化学成分分析等手段，研究7A04和2A97在典型气候环境中的性能演变规律。结果 对于7A04铝合金，经过2 a的湿热海洋气候环境试验后，表面出现均匀腐蚀，抗拉强度、伸长率下降，硬度无变化；经过2 a的湿热雨林气候环境试验后，外观形貌、抗拉强度、硬度无变化，伸长率下降；经过2 a的暖湿酸雨气候环境试验后，表面出现点蚀，抗拉强度、硬度无变化，伸长率下降。对于2A97铝合金，经过2 a的湿热海洋气候环境试验后，表面由点蚀发展为局部腐蚀，抗拉强度、伸长率下降，硬度无变化；经过2 a的湿热雨林气候环境试验后，外观形貌、抗拉强度、伸长率、硬度无变化；经过2 a的暖湿酸雨环境试验后，外观形貌、硬度无变化，抗拉强度、伸长率下降。结论 湿热海洋和暖湿酸雨气候环境对7A04和2A97易造成腐蚀，而湿热雨林气候环境对7A04和2A97不易造成腐蚀，2A97的耐蚀性优于7A04。 |

| This paper aims to study the effects of typical climate conditions such as hot and humid ocean, humid rain forest and warm wet acid rain on properties of 7A04 and 2A97.Through outdoor exposure test of 7A04 and 2A97 aluminum alloy sample was carried out. Appearance observation, mechanical property testing, chemical composition analysis were combined to study the performance evolution of 7A04 and 2A97 in typical climatic environment. After two years’ testing under hot and humid ocean, the surface of 7A04 appeared uniform corrosion, the tensile strength and elongation decreased, the hardness did not changed; After two years’ testing under hot and humid rain forest, the appearance, the tensile strength and the hardness did not changed, the elongation decreased; After two years’ testing under warm wet acid rain, the surface appeared pitting corrosion, the tensile strength and hardness did not changed,the elongation decreased. After two years’ testing under hot and humid ocean, the surface of 2A97 developed from pitting corrosion to local corrosion, the tensile strength and elongation decreased, the hardness did not changed; After two years’ testing under hot and humid rain forest, the appearance, the tensile strength, the elongation and hardness did not changed; After two years’ testing under warm wet acid rain, the appearance and hardness did not changed, the tensile strength and elongation decreased. 7A04 and 2A97 are easy to be corroded by hot and humid ocean and warm wet acid rain climate environment, while 7A04 and 2A97 are not easy to be corroded by hot and humid rain forest climate environment 2A97 has better corrosion resistance than 7A04. |
