流化床热处理在15年前商业化地引入金属处理行业。从那时起，流化床技术的固有特性导致了渗氮、氮碳共渗、硬化和渗碳热处理工艺的进步。本文将综述流化床热处理的应用现状、设备和其他操作方面。

Fluidized bed heat treating was introduced commercially to the metal treating industry over 15 years ago. Since that time, the inherent characteristics of fluidized bed technology have led to advances in nitriding, nitrocarburizing, hardening and carburizing heat treating processes. This paper will review current application, equipment and other operating aspects of fluidized bed heat treating.
