Abstract

Temperature and pH influence on uniform corrosion of 2024-T3 aluminum alloys is reported through a series of free immersion tests. Extensive results performed in various pH (3 to 10), Cl-, and temperatures (20°C to 80°C) from 1 day up to 1 month are reported to mimic real applications. A comparison with weight loss experiment is demonstrated to provide a quantitative significance of pitting versus uniform corrosion. Severity of uniform corrosion is measured at various pH, temperature, and time. Electrochemical approaches including electrochemical impedance spectroscopy (EIS) and cathodic polarization are utilized characterizing oxygen reduction reaction (ORR) and passivation at different temperatures. Passive film and corrosion product analysis is conducted by electron microscopies to assess microstructure, morphology, and corrosion product formation driven by temperature.
