摘要
在无镍白铜中加入Sn和Al获取新型无镍白铜合金。采用光学显微镜、扫描电子显微镜(SEM)观察合金的显微组织;通过脱锌腐蚀实验、电化学腐蚀实验评价该合金的耐腐蚀性能;通过拉伸实验和硬度实验检查力学性能是否发生变化。结果表明,加入微量Sn和Al可明显改善合金的耐腐蚀性能,且能略微的改善合金的力学性能。
A new Ni-free white copper alloy was designed by alloying with Sn and Al.The microstructure of the alloy was observed by optical microscopy and scanning electron microscopy(SEM).The corrosion resistance of the alloy was evaluated by dezincification corrosion test and electrochemical corrosion test.The mechanical properties were examined by tensile test and hardness test.The results show that the addition of trace Sn and Al can significantly improve the corrosion resistance and slightly improve the mechanical properties of the alloy.
