In this study, corrosion properties of AA2024 aluminum alloy matrix composite materials reinforced with Al2O3 in three different ratios were investigated. After mixing the aluminum alloy matrix material powders and the reinforcement material powders at 10%, 20% and 30% Al2O3 ratios homogeneously, composite materials were produced by keeping them in an axial mold under 50 MPa pressure and 550 °C for 1 hour by hot pressing method. According to the corrosion test results, the corrosion resistance of the composite materials containing 20% and 30% Al2O3 reinforcement was very close to each other. The corrosion rates of these two samples were determined to be lower than the sample containing 10% Al2O3 reinforcement.
