由于渗硼处理后渗层具有高硬度、高耐磨性、耐热性、耐蚀性和红硬性等,因此受到了热处理工作者的重视。近年来,我国许多单位把渗硼工艺用于生产实践,取得了可喜的成果。但是,都偏重于渗硼工艺方法的探讨,而对渗硼的机理和硼化物层的生长机构却很少研究。本文就渗硼过程中存在着某种竞争反应的可能性问题,提出一些不成熟的看法,供大家探讨。一、过渡层中富集的碳并不 Due to the infiltration of boron after treatment with high hardness, wear resistance, heat resistance, corrosion resistance and red hardness, so by the heat treatment workers attention. In recent years, many units in our country use boronizing technology for production practice and have achieved gratifying results. However, the emphasis is placed on the exploration of the technological process of boronizing. However, the mechanism of boronizing and the growth mechanism of boride layer are rarely studied. In this paper, there is a possibility of competition in the process of boron infiltration, put forward some immature views for your discussion. First, the transitional layer is not rich in carbon
