具有国际先进水平的“气体低温稀土多元共渗”新工艺,在我校副教授吕振家等老师的刻苦钻研下,经过了无数次的试验,研试成功了。 这项新工艺打破了“关于半径过大的原子不能渗入到钢铁材料中去”的传统观点,经过反复的大量的实验,证明:大尺寸稀土原子不仅能够渗入到钢铁材料中去,而且能促进碳、氮、硼等原子的渗入。同时还具有成本低、设备操作简单、低温等特点。 这项新工艺,经丹东手表工具厂在条轴丝锥和薄片铣刀上应用,证明可分别提高使用寿
The internationally advanced “gas low temperature rare earth multivariate infiltration” new technology, in our school associate professor Lv Zhenjia and other teachers of painstaking research, after numerous tests, the test was successful. This new process, breaking the traditional notion that atoms with too large a radius can not penetrate into steel, has proved that large-sized rare-earth atoms can not only penetrate into steel but also promote Carbon, nitrogen, boron and other atoms infiltration. At the same time also has low cost, simple equipment, low temperature and so on. The new technology, the Dandong Watch Tools Factory in the axis of the tap and slice cutter application, that can improve the service life
