A thermodynamic evaluation of nitrocarburizing atmospheres
Steel Research, 1995Knowledge of the thermodynamics of ammonia reforming in complex gases should be valuable for the control of nitrocarburizing processes. In this papersome gas mixtures based on N + H + O and/or N + H + O + C systems are discussed. From the equilibrium behaviour of these gas mixtures the nitrogen potential can be derived.

Gaseous Ferritic Nitrocarburizing
2003Abstract Gaseous ferritic nitrocarburizing, like salt bath nitrocarburizing, involves the introduction of carbon and nitrogen into steel in order to produce a thin layer of iron carbonitride and nitrides, the "white layer" or compound layer, with an underlying diffusion zone containing dissolved nitrogen and iron (or alloy) nitrides ...

Low Temperature Ferritic Nitrocarburizing
SAE Technical Paper Series, 1999<div class="htmlview paragraph">Salt bath nitrocarburizing (SBN™) is typically done at 1075°F, thereby limiting near-surface hardening, and consequently fatigue strengthening, according to the temper resistance of the base material. The first phase of this investigation is a study of the response of low alloy steels to SBN at lower temperatures ...

Preparation for Ferritic Nitrocarburizing
2003Abstract Surface cleanliness requirements depend on which nitrocarburizing process is selected for component treatment. This chapter discusses the processes involved in some of the more commonly used precleaning methods for gas ferritic nitrocarburizing and provides information on the methods used to accomplish enhanced plasma cleaning.

Ferritic Nitrocarburizing Processes and Applications
Heat Treating Conference, 2013Abstract Ferritic Nitrocarburizing and nitriding processes are available in various atmosphere blends and a myriad of equipment designs. Atmosphere choices can dictate process capabilities. Equipment design should be reviewed to select the proper choice for the part application.
