对钢铁零件进行渗碳处理来改变其表面性能的方法可以追溯到铁器时代初期,在基本原理不变的前提下,人们一直致力于改革传统的工艺和开发新的工艺来获得良好的质量控制、较好的结果予测和比较稳定的结果。为了提高表面渗碳的生产率,减少工件的积压,降低成本,在不同的周期里处理多种工件,建立及时处理的概念,得到高质量的工件,需要设计出新的设备和制订新的工艺。能满足上述要求的新的发展包括高温渗碳、等离子体(离子)渗碳、真空渗碳和采用更为灵活的连续式炉。
Carburizing steel parts to change the surface properties of the method can be traced back to the Iron Age, under the premise of the same basic principles, people have been committed to reforming the traditional process and the development of new processes to obtain good quality control, Better results to predict and more stable results. In order to improve the productivity of surface carburizing, reduce the backlog of parts, reduce the cost, handle many kinds of workpieces in different cycles, establish the concept of timely processing and get high-quality workpieces, we need to design new equipment and formulate new processes. New developments that meet these requirements include high temperature carburization, plasma (ion) carburizing, vacuum carburizing and the use of more flexible continuous furnaces.
