| 中文摘要: |
| 采用扫描电子显微镜(SEM)、表面电子探针显微分析仪、电接触性能试验机等手段，研究了混粉法和包覆法制备的AgSnO2电接触材料在直流条件下(DC 24 V/15 A)，铆钉触头表面的电弧烧蚀情况。对材料的表面烧蚀机理、金属转移情况，以及电寿命等进行了讨论。结果表明，包覆法制备的AgSnO2电接触材料具有较强的耐电弧侵蚀能力与较少的材料转移量。 |
| 英文摘要: |
| The arc erosion resistance property on the surface of AgSnO2 electrical contact materials prepared by mechanical mixing and coating method under the condition of the DC(DC 24 V/15 A) were studied by a scanning electron microscope (SEM), surface electron probe microanalyses and electric contact performance testing machine, etc. The material surface arc erosion mechanism, the metal transfer, and electric life were discussed. The result showed that cladding of AgSnO2 electricity contact materials prepared by the arc erosion resistance ability is strong and less material transfer, etc. |
