铅银和铅银镧合金作为正极板栅的性质研究

A sort of Mo-La_2O_3 alloy strengthened with lanthanon's dispersion was gained by adopting a special preparation method to have the forerunner powder and one adulteration way of liquid & solid.

采用特殊制备前驱粉和液-固掺杂方式制备出弥散强化稀土钼镧合金,通过扫描电镜和透射电镜,研究了掺杂方式对钼镧合金烧结体中第二相的粒度分布和形貌,证实了钼基体中La2O3颗粒的存在,分析了第二相粒子在钼基体中的分布规律,测定了钼丝的拉伸性能,根据奥洛万机制,引入位错可滑移宽度的概念,分析了粒子尺度对材料硬化性能的影响,提出了改进小尺度第二相粒子强化钼合金加工性能的建议。

Electrodeposition of cobalt and La-Co alloy from urea-NaBr-KBr-formamidesystem containing co (Ⅱ) or co (Ⅱ) +La (Ⅲ) is investigated.

研究了在含Ｃｏ（Ⅱ）或含Ｃｏ（Ⅱ）＋Ｌａ（Ⅲ）的尿素－ＮａＢｒ－ＫＢｒ－甲酰胺体系中钴和镧钴合金的电沉积过程。
