This study aims to investigate the wear and corrosion resistance after heat treatment of AA2010 alloy. AA2010 alloy was solutionized at 500 °C for 1 h, and then quenched in water at room temperature. Solu-tion treatment was followed by aging treatment at 160 °C for 16, 18, and 22 h. Peak hardness was achieved at 18 h. Ball-on-disc wear test caused cold deformation and hence increased the hardness of the worn surface lo-cally. The corrosion rate of heat treated AA2010 alloy was determined according to Tafel extrapolation meth-od. Corrosion test was carried out in 3.5 wt.% NaCl solution at room temperature. The minimum corrosion rate was obtained in 18 h aged AA2010 alloy. For moderate wear resistance and good corrosion resistance, 18 h aging is recommended for AA2010 alloy. Both the intergranular and pitting corrosion mechanisms were observed on the corroded surface of the AA2010 alloy.
