本文根据工厂新产品开发的需要,在工厂原有离子渗氮的基础上,试验出一种新的氮碳共渗工艺,即NH_3+CO_2离子氮碳共渗。文章介绍了该工艺的理论依据、生产条件和操作控制方法。在离子渗氮的基础上采用该工艺,操作简单、质量稳定、成本低、无污染。该工艺不仅满足了工厂新产品开发的需要,而且得到广泛的应用。 Based on the original ion nitriding in our factory, a new nitrocarburizing process, namely NH3 + CO2 nitrocarburizing, was tested according to the needs of new product development in our factory. The paper introduces the theoretical basis of the process, production conditions and operational control methods. The ion nitriding based on the use of the technology, simple operation, stable quality, low cost, pollution-free. The process not only meets the needs of the development of new products factory, but also widely used.
