Abstract

In this paper, the corrosion resistance and mechanical properties of the 7075 aluminum alloy are studied. The alloy was deformed by hydrostatic extrusion and then aged both naturally and artificially. Results are compared with those of coarse-grained material subjected to T6 heat treatment. The aim of the research is to find the optimal correlation between the mechanical properties and the corrosion resistance of the alloy. To this end, static tensile tests with subsequent fractography, open circuit potential, and potentiodynamic polarization tests in 0.05 M NaCl were conducted. Obtained results show that a combination of precipitate hardening and a deformed microstructure leads to increased mechanical strength with high anisotropy due to the presence of fibrous grains. Plastic deformation increases susceptibility to corrosion due to the increased number of grain boundaries, which act as paths along that corrosion propagates. However, further artificial aging incurs a positive effect on corrosion resistance due to changes in the chemical composition of the matrix as a result of the precipitation process.

摘要

本文研究了7075铝合金的耐腐蚀性和力学性能。该合金通过静水挤压变形，然后进行自然时效和人工时效。将结果与经过T6热处理的粗晶材料的结果进行比较。研究目的是找到合金力学性能与耐腐蚀性之间的最佳关联。为此，进行了静态拉伸试验及随后的断口分析、开路电位测试以及在0.05 M NaCl溶液中的动电位极化测试。所得结果表明，沉淀硬化和变形微观结构的结合导致由于纤维状晶粒的存在而具有高各向异性的机械强度增加。由于晶界数量增加，塑性变形会增加对腐蚀的敏感性，晶界充当了腐蚀传播的路径。然而，由于沉淀过程导致基体化学成分发生变化，进一步的人工时效对耐腐蚀性产生了积极影响。
