Abstract
This paper is dedicated to studying the effect of solid-solution process on the properties of 7050 aluminum alloy. First, the 7050 aluminum alloy samples were treated under different solid-solution processing conditions (460 ° C × 90 min, 470 ° C × 90 min, 460 ° C × 90 min + 470 ° C × 30 min and 460 ° C × 90 min + 470 ° C × 60 min). Then, the properties of different samples were tested. In this step, the metallographic structure of the samples were observed by an optical microscope, the hardness were measured by a Vickers hardness tester, the wear resistance were measured by a friction and wear tester, and the corrosion resistance was tested by an electrochemical workstation. Finally, experimental results confirm that 7050 aluminum alloy has the best wear resistance and corrosion resistance, in solid-solution processing conditions of 460 ° C × 90 min + 470 ° C × 60 min.
