| 中文摘要: |
| 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。 |
| 英文摘要: |
| 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. |
