氮化处理工艺原本是一种低温下的热处理,它容易与其他各种处理进行复合使用。文章介绍了氮化与真空渗碳淬火、氮化与硬质材料涂覆、氮化与氧化及硬质材料涂覆等几种实用的复合处理工艺方法和这些方法具体的操作过程。此外,也论述了上述复合热处理广泛的应用与效果。 Nitriding process was originally a low-temperature heat treatment, it is easy to compound with a variety of other treatments. In this paper, several practical composite treatment methods such as nitriding and vacuum carburizing and quenching, nitriding and hard material coating, nitriding and oxidation and hard material coating are introduced, and the specific operation procedures of these methods are introduced. In addition, the extensive application and effect of the above composite heat treatment are also discussed.
