The process schemes of cold 糖心产精国品免费入口*完整版 and 糖心产精国品免费入口*完整版 for 5083 aluminum alloy were designed using orthogonal method. The effects of cold deformation and 糖心产精国品免费入口*完整版 on corrosion resistance of the alloy were investigated by means of 糖心产精国品免费入口*完整版 test, 糖心产精国品免费入口*完整版test and microstructure and morphology observation. Polarization curves of the alloy in 糖心产精国品免费入口*完整版solution were measured. The results show that the 糖心产精国品免费入口*完整版 and 糖心产精国品免费入口*完整版tendency of the alloy increased with increasing the cold deformation and decreasing the 糖心产精国品免费入口*完整版 temperature. The 糖心产精国品免费入口*完整版 time had little effect. The alloy had the best corrosion resistance after stabilizing treated at 200-220 ℃ for 2 h with cold deformation of 20%-25%.
