摘　　要：开发了高温高真空气雾化技术 ,并利用该技术制备了CuCr5 0合金化粉末 ,对合金粉末的相貌、微观组织和合金元素成分分布进行了分析。研究结果表明 :粉末球形度高 ,合金化状况良好 ,微观组织均匀 ,Cr析出相细小 ,有利于提高触头材料的综合使用性能。A high temperature and high vacuum gas atomization technology was developed. CuCr50 alloy was produced by gas atomization technology. The shape, microstructure and distribution of element in powder were studied. The results show that the shape of powder is spherical, Cr phase is fine and dispersive, the microstructure of powder is fine and uniform. All of these results are favourable for improving the comprehensive performance of contact materials.
