What is Salt Bath Nitriding?

Salt bath nitriding, also known as ferritic liquid ion nitriding or nitro-carburization is a process in which nitrogen and carbon are diffused into the surface of ferrous metals. The diffusion of these elements gives the metal enhanced mechanical properties compared with untreated steel. The process involves pre-heating the untreated steel material which is then placed in a liquid salt bath where the nitrogen and carbon are diffused into the surface of the material. The part is then quenched in another liquid bath for black oxide treatment and finally rinsed and cleaned. The resulting part benefits from an aesthetic black color as well as some of the enhanced properties listed above.
