摘　　要：通过金相显微镜、透射电镜及电化学法探讨了高压处理对铝青铜在3.5%NaCl溶液中耐腐蚀性的影响。结果表明:4 GPa高压力处理能细化铝青铜的组织及增大位错密度,降低耐腐蚀性。The effects of high pressure treatment on the corrosion resistance of aluminum bronze in 3.5% NaCI solution were studied by metallographic microscope, transmission electron microscopy and electrochemical method. The results show that the grains can be refined under 4 GPa pressure treatment and then the dislocation density increases, and the corrosion resistance of the aluminum bronze decreases.
