中文摘要:
      在海南万宁试验站开展2D12铝合金海洋大气暴露试验, 通过质量损失分析、 力学性能分析和金相显微形貌分析, 研究了2D12铝合金在海洋大气环境中腐蚀的规律和行为。结果表明, 2D12铝合金的腐蚀质量损失与暴露时间的关系可用幂函数回归; 随暴露时间的延长, 2D12铝合金的抗拉强度先下降、 后趋于平稳, 断后伸长率则逐渐降低; 金相显微分析表明, 2D12铝合金的腐蚀由初始的点蚀逐渐发展成晶间腐蚀。
英文摘要:
      Marine atmospheric exposure test of 2D12 aluminum alloy was carried out in Wanning exposure site. The corrosion rule and behavior of 2D12 aluminum alloy were investigated by weight loss, mechanical property, and micrographic morphology analysis. The result showed that the relationship between weight loss and exposure time of 2D12 aluminum alloy can be regressed by power function; the tensile strength of 2D12 decreases first with exposure time and then reach balanced with further increasing exposure time; the percentage elongation after fracture of 2D12 decreases with increasing exposure time. The micrographic morphology analysis showed that 2D12 aluminum alloy corrosion develops from pit corrosion into intergranular corrosion.
