采用金相分析、硬度测试、动电位极化技术、颜色分析等手段,研究了含锗合金与传统斯特林银在显微组织和冷加工、抗电化学腐蚀、抗氧化变色、抗硫化变色等性能方面的不同。结果表明:锗含量在0.2%～0.8%之间,合金具有较好的综合性能,且当含量为0.5%时,合金的铸态硬度较高,冷加工性能、抗电化学腐蚀性能和抗变色性能相对更优。 The effects of microstructure and cold working, anti-electrochemical corrosion, anti-oxidation and anti-sulfur discoloration of germanium-containing alloy and traditional Stirling silver were studied by means of metallographic analysis, hardness test, potentiodynamic polarization and color analysis Different performance. The results show that the content of germanium is between 0.2% and 0.8%, the alloy has good comprehensive properties, and when the content is 0.5%, the as-cast alloy has higher as-cast hardness, cold working property, electrochemical corrosion resistance and discoloration resistance Relatively better.
