| 摘 要： | 抗电弧侵蚀性能是衡量电接触材料好坏的一个重要指标.本文对采用反应合成技术制备的AgSnO2电接触材料进行电接触试验,并通过扫描电镜观察材料在电弧侵蚀后的形貌,对AgSnO2(10)材料在直流、阻性负载条件下的电弧侵蚀特征进行研究.结果表明,反应合成法制备的AgSnO2(10)电接触材料在电流≤20A条件下,材料由阴极向阳极转移;电流＞20A条件下,材料的转移方向反转.归纳出电弧侵蚀后的AgSnO2(10)的表面形貌特征.

| Abstract: | The electrical contact tests were carried out for silver tin oxide electrical contact materials which were fabricated by reactive synthesis.The electrical erosion performances of AgSnO2(10) under DC and resistance loads conditions were studied.The morphology of AgSnO2(10) after arc erosion were investigated by means of scanning electronic microscopy(SEM).The results indicated that the anode gains mass when current value is less than 20A;and the anode losses mass when current value is more than 20A.The surface morphologies of AgSnO2(10) contacts were classified. |
