This work aimed to study the corrosion resistance of aluminum alloy 2024 – T6 at multi variable temperatures and velocities in seawater. 2024-T6 is widely used in aircraft structures, especially wing and fuselage structures under tension. The specimens were manufactured by dimensions of 1.5 cm length x 1.5 cm width x 0.2 cm thickness, According to ASTM (G71-30). Corrosion test was implemented by using potentiostatic polarization measurements in seawater 3.5%NaCl at a temperature of 25°C, 50°C and 75°C , velocity 1, 2, 3 m/min . The potential of circuit was determined by open circuit depending on AL in electrochemical series after that the rate of cell’s current is changed due to 100± (m v). From result which obtained by Tafel equation. It was found that the corrosion resistance of 2024 – T6 Al alloy, increases with increasing velocity and decreases with increasing of temperature.

Keywords: Corrosion resistance, aluminum alloy, velocity, temperature, seawater.
