摘要

在本工作中，根据ASTM G34-01标准，对7150-T77高强度合金的腐蚀敏感性进行了EXCO腐蚀试验，该标准涵盖了7XXX系列铝合金的剥离腐蚀试验程序。当使用7xxx系列合金时，腐蚀可能是限制飞机机体寿命的一个重要来源，这就是为什么它们要在专门的实验室中进行系统的腐蚀测试。

SUSCEPTIBILITY AT THE CORROSION OF 7150-T77 ALUMINUM ALLOY USED IN AVIATION INDUSTRY

In this work, has been performed the susceptibility to corrosion on high strength alloy of 7150-T77 at the EXCO corrosion test according to ASTM G34-01 standard which covers a procedure for exfoliation corrosion testing of 7XXX series aluminum alloys.Corrosion it can be an important source of limiting the life of the aircraft body where alloys from the 7xxx series are used, which is why they are systematically subjected to corrosion tests in dedicated laboratories.
