摘要
本文研究了不同稀土含量对粉末渗硼层深的影响。试验结果表明,粉末渗硼剂中加入稀土元素均有催渗作用,并存在一个起明显催渗作用的最佳值。本章分析了稀土含量对渗硼过程动力学及表层硬度的影响,对稀土催渗机理进行了探讨。
The effect of rare-earth elements on the thickness of Powder boriding Layeer was studied in this paper. Experimental results show that the Re inr boriding agents Can catalyze boriding psocess and there is a ramarkable optimum Re guantity. The effects of rare-earth on the kinetice in boriding piocess and surfare hardness of samples were studied andthe catalyzing Mechanism of Re Was discussed in this paper either
