摘要
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,导致渗层孔洞增加。
By thermodynamics analysis the paper shows that the retained H_2O and O_2 in the atmosphere not only lose the boronizing ability of BCl_3 and B atoms but also consume more BCl_3 used, accelerate the formation of Fe-Cl compound and lead to more layer voids.
