摘　　要： 通过金相﹑扫描电镜(SEM/EDS)、X射线衍射仪及电化学等方法对Cu-Zn合金经高压处理后的组织演化及耐腐蚀性能进行研究。结果表明,Cu-Zn合金在25～750℃,1～6GPa范围压力下的相变体积分数随压力的增大先增加后减少,当压力为3GPa时,相变体积分数最多,获得的组织较细小,合金抗腐蚀性能最差,压力为6GPa时,合金抗腐蚀性能最好,合金的耐腐蚀性能与其组织有较好的对应关系。 Microstructure evolution and corrosion resistance of Cu-Zn alloy after high pressure treatment were studied by means of Metallograph, SEM/EDS, XRD and electrochemical method. The results show that in the temperature range of 25-750 ℃ and the pressure range of 0-6 GPa, the volume fraction of transformation phase of Cu-Zn alloy increases and then decreases with increasing pressure; for the specimen after 3 GPa high pressure treatment, the most volume fraction of transformation phase and finer microstructure are obtained, and the corrosion resistance is the worst, while the specimen after 6 GPa high pressure treatment performes the best corrosion resistance As a result, the corrosion resistance of Cu-Zn alloy is perfect corresponded with its microstructure.
