气体渗硼的热力学分析

Thermodynamics Analysis of Gaseous Boronizing

本文通过热力学分析表明,在BCl_3+H_2介质中进行气体渗硼时,气氛中残留的H_2O、O_2不仅使BCl_3和B原子失去渗硼能力,加大了BCl_3的消耗,而且加剧了Fe-Cl化合物的生成,导致渗硼层孔洞增加。

By thermodynamics analysis the paper shows that during gaseous boronizing for the medium of BC_3+H_2, the retained H_2O and O_2 in the atmosphere not only can make BCl_3 and B atoms lose their boronizing ability but also consume more BCl_3, accelerate the formation of Fe-Cl compound and lead to more Boronized layer voids.
