Salt Bath Ferritic Nitrocarburizing

Abstract

Ferritic nitrocarburizing is a diffusion process that is a modified form of nitriding, not a form of carburizing. The key elements of the process are: temperature, time, suitable nitrogen source, suitable carbon source, and sealed and controlled environment. This chapter provides a detailed discussion on methods of salt bath nitrocarburizing. These include low-cyanide salt bath ferritic nitrocarburizing, salt bath nitrocarburizing plus post treatment, and Kolene Nu-Tride process.
