摘要
钯钨合金具有高的电阻率、低的电阻温度系数和对铜热电势、稳定的接触电阻,以及良好的耐磨性和抗腐蚀性,常用作精密电位计和电位器的绕线电阻丝,广泛应用于航天、航海、以及军事方面,但国内外关于钯钨合金的研究报道却较少。本文介绍了Pd-W系合金的相图,并总结其性能、制备、研究现状及合金熔炼可能的改进方法。
Palladium-tungsten alloy has high electrical resistivity,low temperature coefficient of resistance and good wear resistance.It is often used as a resistance wire for precision potentiometers.It has great applications in aerospace,marine,and military applications.However,there are few research reports of palladium-tungsten alloy at home and abroad.This article will introduce the phase diagram of Pd-W alloy and summarize its performance,preparation,research and possible future development paths.
