随着渗硼工艺的应用日趋广泛,解决渗硼层脆性已是当务之急。目前降低脆性的有效方法是进行共晶化渗硼处理,以得到软硬相配的组织,取代普通渗硼由硬脆相组成的连续硼化物层。但此工艺若在炉中进行,则加热时间长,基体组织也会因加热温度高而粗化。我们从1981年开始在高频上进行一次加热获得共晶型渗硼层的试验工作,探索出一些规律,获得了成功。这种 With the increasingly widespread application of boronizing process, to solve the brittleness of boronizing layer is a top priority. At present, an effective method to reduce the brittleness is to perform eutectic and boronizing treatment so as to obtain a soft and hard matching structure instead of a continuous boride layer composed of a hard and brittle phase which is ordinary boronizing. However, if the process carried out in the furnace, the heating time is long, the matrix will be due to high heating temperature and coarse. We started in 1981 at high frequency to obtain a heated eutectic boronizing layer test work to explore some of the rules and achieved success. This
