强化型纯铂材料性能研究

摘要

The purity and the morphology of strengthened pure platinum and the way of fine wire preparation were reported by adding trace R element. The related performances of strengthened pure platinum wire were compared with sponge platinum wire. The thermoelectric properties of strengthened pure platinum fine wire is in accordance with national standards and user requirements.%针对纯铂微细丝的加工难点，探讨了在有微量元素R存在时强化型纯铂微细丝的原料纯度和微观形貌，以及微细丝的研制方法，并就强化型微细丝和海绵铂微细丝的有关性能进行了对比；研制的强化型纯铂微细丝，其热电性能符合国家标准，满足用户需求。
