| Zusammenfassung: | 本发明提供一种钼硅硼固溶强化钼切割丝及其制备方法，包括钼基体和固溶入钼基体内的Mo5SiB2，Mo5SiB2质量占钼基体质量的0.9％～1.3％。以二氧化钼粉末为前驱体，加入Mo5SiB2，通过氢气还原制备得到。本发明采用Mo5SiB2金属陶瓷化合物做为钼金属强化剂，提高电极钼丝抗电弧腐蚀性。
The invention provides a molybdenum-silicon-boron solid solution reinforced molybdenum cutting wire and a preparation method thereof, the molybdenum-silicon-boron solid solution reinforced molybdenum cutting wire comprises a molybdenum matrix and Mo5SiB2 solid-dissolved in the molybdenum matrix, and the mass of Mo5SiB2 accounts for 0.9%-1.3% of the mass of the molybdenum matrix. Mo5SiB2 is added into molybdenum dioxide powder serving as a precursor, and the catalyst is prepared through hydrogen reduction. According to the invention, the Mo5SiB2 metal ceramic compound is used as a molybdenum metal enhancer, so that the arc corrosion resistance of the electrode molybdenum wire is improved. |
