The corrosion behavior of 6063 alloy with different aged treatment was investigated by hardness test,intergranular corrosion test,total immersion corrosion test and electrochemical corrosion test,meanwhile,the corrosive mechanism was analyzed.The results show that with increasing in aging temperature,the time of intergranular corrosion and homogeneous intergranular corrosion are shortened,and the maximum corrosion depth is decreased.The dynamic potential polarization of the 6063 alloy at different aging treatment is accordant with the intergranular corrosion test,total immersion corrosion test,where the corrosion resistance of the alloy is gradually decreased from under-aging,peak aging to over aging.
