MATERIAL - ALUMINUM - 2024-T86 CORROSION EVALUATION, SERVICE ITEMS

Abstract

Two F-102 airplane wing access doors received about five years subsequent to manufacture were examined for corrosion damage incidence. The doors were made of cladT86 aluminum alloy and their exterior surfaces were originally treated with Alodine 600 chemical and coated with a baked Scotchweld primer. Upon receipt, the primer was missing from interior surfaces accessible to fuel impingement. These areas ex hibited corrosion pitting ranging 6 to 35 mils depth and 20 to 120 pits per door as a result of general corrosive attack which appeared to have been caused by marine atmosphere impingement. Examination revealed that the clad 2024-T86 aluminum alloy was normal with respect to inter granular corrosion susceptibility.
