复合热处理,也称作双重或混合技术,提供了具有新的组织/性能关系的基体化合物层,而处理工序是关键。这种技术能达到单项处理工艺或单项工艺的简单叠加所不能达到的性能和性能梯度、化学热处理与高能束表面淬火特别是电子束淬火相结合,使这项技术取得了显著进展。本文在评述热化学与热(表面)处理技术相结合的历程(重大事件)后,介绍了渗氮后进行电子束淬火和电子束淬火后进行渗氮的原理及其对微观组织与性能的影响,并讨论了典型的工业应用实例。该领域的进一步发展主要是高能束(电子束或激光束)淬火与硬质涂层技术相结合。
Compound heat treatment, also referred to as dual or hybrid technology, provides a layer of matrix compound with new tissue / property relationships that is critical to the process. This technology achieves performance and performance gradients that can not be achieved with simple overlays of individual processes or individual processes. The combination of chemical heat treatment with high-energy surface hardening, especially e-beam quenching, has led to significant advances in this technology. After reviewing the history (major events) of thermochemical and thermal (surface) treatment, this paper introduces the principle of nitriding after nitriding electron beam quenching and electron beam quenching and its effect on microstructure and properties , And discussed a typical example of industrial applications. A further development in this area is the combination of high energy beam (electron beam or laser beam) quenching with hard coating technology.
