Abstract

Samples were taken from a forged deformation 6082 aluminum alloy control arm center, and were heat treated by solid solution at 510-590 ℃ and aging at 175 ℃. The effects of solution temperature on microstructure, hardness, and friction wear properties under loads of 2.8 and 6.8 N were studied. The results show that heat treatment improved the hardness and wear resistance of the alloy. With the increase of the solution temperature, the hardness of the alloy increased. When the temperature was 550 ℃, the alloy had the smallest grains and the highest hardnesss. As the temperature continued to rise, the grains became coarse, and the hardness decreased.The wear volume at 550 ℃ solution temperature was the smallest under the two loads. The wear mechanism of the samples with different heat treatments under the two loads was abrasive wear. Micro cracks and furrows appeared on the wear surfaces.
