| 摘要: |
| 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，但固体渗碳层偏包薄，时间较长，只能适应单件、小批量的生产。 |

| Abstract: |
| The experiment of solid-carburizing process on 20 steel and 20CrMoV steel has been fully developed,which includes prepartory 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 spcial devices.The solid-carburizing product completely meets conventional requirement.However,solid-carburizing process has its disadvantages such as thin carburizing coating and too long totl operating time,thus solid-carburizingonly fits for ghe production of single-piece on small scale. |
