| 摘 要： | 采用力学性能测试、光学显微镜、扫描电镜和能谱分析技术、切削性能测试、电镀试验对自行配制的含Bi易切削变形Zn-Al合金铸态、挤压态的组织与性能进行研究.研究结果表明:低熔点的Bi相在Zn-Al合金中以针状弥散分布,改善Zn-Al合金的切削性能；Bi含量超过0.5％(质量分数)时,Bi对Zn-Al易切削变形合金电镀性能产生不良影响；自行配制的Zn-10％Al-0.3％Bi-X合金,切削性能良好,抗拉强度达到351 MPa,伸长率为18％,电镀不易起泡,表现出较好的综合性能,可作为部分铜合金替代材料,用于轴承、连接件、五金、家电等结构件.

| Abstract: | The microstructure and properties of self-developed free-cutting deformation Zn-Al alloys containing Bi in the cast and extruded conditions were investigated by mechanical tests,optical microscopy,scanning electron microscopy,energy spectrum analysis,machinability tests and plating performance tests.The results show that the machinability of the Zn-Al alloy can be improved by needle dispersion distributed low-melting Bi phase.The plating performance of free-cutting deformation Zn-Al alloys gets worse when t... |
