对20、20CrMoV钢的固体渗碳进行了较全面的实验及研究,包括钢的预备热处理、渗碳工艺、金相组织、最终热处理等;分析了渗碳层、硬度的影响因素,并总结摸索出固体渗碳的基本规律和工艺技术;实验证明：固体渗碳工艺简单、操作简单、成本低廉,不需要专门设备;渗碳件在性能上完全能够达到常规渗碳的要求,但固体渗碳的渗碳层偏薄,时间较长,只能适应单件、小批量的生产。

The experiment of solid-carburizing process on 20 steel and 20CrMoV steel has been fully developed, which includes preparatory heat-treatment, carburizing craft, metallographic structure, the final heat- treatment, etc. This experiment analyzed the factors of carburizing coating and hardness, and the basic law and technology of solid- carburizing process have been worked out. The experiment has proved that solid- carburizing craft has several advantages such as simple process, easily to operate and control, low cost, and without special devices. The solid- carburizing product completely meets conventional requirement. However, solid-carburizing process has its disadvantages such as thin carburizing coating and too long total operating time, thus solid- carburizing only fits for the production of single-piece on small scale.
