影响整体式铜—钨合金触头质量的因素

本文讨论了铜钨合金的化学成分、钨粉颗粒度及其配比、宏观硬度、密度、显微组织和缺陷等对整体式粉末冶金铜-钨触头性能的影响。作者认为,显微组织分析是控制和判断粉末冶金铜-钨触头质量的重要方法之一。

FACT ORS EFFECTING ON QUALITIES OF INTEGRAL P/M COPPER-TUNGSTEN ALLOY CONTACTORS

The present paper describes the effects of chemical compositions of Cu-W alloys, particle sizes of tungsten powder and its distribution, macrohardness,densities, microstructure and defects etc, on the properties of P/M copper-tungsten alloy contactors. The analyses of microstructure is one of the important methods for controlling and evaluating the qualities of copper-tungsten alloy contactors。
