摘要

本研究探讨了 T6 热处理、两步时效处理和超声波冲击强化对焊接 EN AW 7020 的剥落腐蚀行为的影响。剥落试验是根据 ASTM G34-01 标准进行的。不出所料，试验结果表明，所有三个样品的母材区域都比热影响区域表现出更好的耐腐蚀性。据观察，超声波冲击强化和两步时效处理提高了焊接区域的 EXCO 灵敏度。根据样品热影响区的耐腐蚀性能进行分类，发现经过两步老化处理的样品耐腐蚀性能最好，而经过 T6 热处理的样品耐腐蚀性能最差。

Exfoliation behavior of EN AW 7020 with T6, step aging and ultrasonic impact peening processes

In this study the effect of T6 heat treatment, two-step aging treatment and ultrasonic impact peening on the exfoliation corrosion behavior of welded EN AW 7020 was investigated. Exfoliation tests were performed according to the ASTM G34-01 standard. As expected, as a result of the tests, the base material region of all three samples were showed better corrosion resistance than the heat-affected region. Ultrasonic impact peening and two-step aging treatment was observed that improved EXCO sensitivity in the weld area. When sorting was made by considering the resistance to corrosion of the heat affected zone of the samples, it was observed that the best resistance was shown by the sample with two-step aging treatment, and the worst resistance was shown by the sample with T6 heat treatment.
