摘　　要：研究了不同温度和不同时间的退火工艺对Al-5Zn-0.02In-1Mg-0.05Ti合金组织和电化学性能的影响。结果表明,经470℃×12 h退火处理的试样组织均匀,晶粒尺寸适中,电化学性能优良。在人造海水中腐蚀后,试样表面的腐蚀产物易脱落,表面均匀平整。随着退火时间的延长,合金的电化学性能逐步提高。The effect of annealing at different temperatures for different times on the microstructure and electrochemical performance of Al-SZn-0.02In-lMg-0.05Ti alloy was investigated. The results show that the specimen provides uniform microstructure, moderate grain size and excellent electrochemical performance after being annealed at 470 ℃ for 12 h. The corrosion product on specimen corroded in a man-made seawater is easy to flake away and the specimen surface is smooth. The electrochemical performance of the alloy will be gradually improved on as the annealing time prolongs.
