Effects of Indium Addition on the Internal Oxidation of Ag-CuO Alloys

Keywords： metal materials , Ag-Cu alloy , internal oxidation , electrical contact material , anti-arc erosion

用合金内氧化法制备了Ag-CuO-In2O3电触头材料样品，采用金相显微镜、扫描电镜及电光分析天平研究了In对Ag-Cu合金内氧化组织和性能的影响。结果表明，添加In可以促进Ag-Cu合金的内氧化，细化晶粒，提高合金的抗电弧侵蚀性能。

Sample of Ag-CuO-In2O3 electrical contact material was fabricated by means of internal oxidation. The analyses about microstructure and feature of Ag-Cu alloys were made through metallurgical microscope and SEM, and the analysis about anti-arc erosion was made through photoelectric analytical balance. The results showed that addition of Indium could refine grain, and increase the rate of internal oxidation and anti-arc erosion of Ag-Cu alloy.
