In this research comparative study between the electrochemical corrosion and erosion-corrosion for two high strengthened aluminum alloys (Al 2024T3 and Al7075T6) was investigated. First corrosion test was performed in seawater (3.5%NaCl solution) using a Tafel extrapolation method and cyclic potentio dynamic polarization tests While the second erosion-corrosion test was carried out in slurry solution (1wt% SiO2 sand in 3.5wt% NaCl solution as the erodent),with varying impact angles (30°, 45° and 90°). It was found that the corrosion rate of Al7075T6 alloy was lower than those of Al2024T3 alloy in case of Tafel extrapolation for polarization test. It was shown that the weight loss rate or erosion- corrosion rate in (gmd) unit for Al7075T6 was lower than that of Al2024T3 at all impact angles during the erosioncorrosion test.
