摘要：

Currently, in the thermochemical treatment practice, different carburizing techniques are used. Among these, the fluidized bed carburizing is a special technique that provides high heat and mass transfer. Also, the fluidized bed accelerates the chemical reaction rates and modifies the carbon adsorption and diffusion in the atmosphere-steel interface. Taking account of both these and of that, the fluidized bed has a rapid heating rate to much higher temperatures, the total process time is reduced significantly. This paper illustrates some data concerning the carburizing mechanism, the fluidized bed carburizing technique in order to illustrate the advantages assured by the fluidized bed carburizing in comparison with conventional carburizing.
