Abstract

The various reactions occurring in nitrocarburizing atmospheres are described and discussed based on thermodynamic principles such as equilibria and reaction kinetics. Utilizing a model for nitriding and nitrocarburizing systems is shown to be beneficial in designing a furnace atmosphere with specific properties, that is, with different nitriding and carburizing properties. Furthermore the influence of different parameters, such as the nitrogen and carbon activities, on the constitution of the compound layer is demonstrated. The analysis of the nitrocarburizing atmosphere and the control of the process are also described and discussed.
