近年来气体软氮化工艺进展很快,已在生产上广泛应用,但仍存在一些问题有待进一步研究解决。为了便于进行此新工艺的研究和生产应用,我们设计和制造了一台小型贯通式气体软氮化炉(图1),使用效果良好。在制造和使用过程中,也发现了一些结构上和操作上的问题。现将其中的几个主要问题加以分析和讨论。
In recent years, gas nitrocarburizing technology has progressed rapidly and has been widely used in production, but some problems still need to be further studied and solved. In order to facilitate the research and production applications of this new process, we designed and manufactured a small through-gas nitrocarburizing furnace (Figure 1) that works well. In the manufacturing and use of the process, but also found some structural and operational problems. Now some of the major issues to be analyzed and discussed.
