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

Abstract

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.
