Plasma Nitriding in general is a heat treating that is used to case harden surfaces using nitrogen. The control of the process par-tial pressure will ensure good root pen-etration of the gear tooth during the ion nitriding cycle, as well as splines, keyways, and bores. Plasma Ion Nitriding is a process for surface treatment of metal parts to make them resistant to wear and fatigue.Parts to be treated are placed in a vacuum chamber and a high DC voltage (typically around 1000 volts) is established between the parts and the chamber wall. Learn more about the different process versions. Plasma nitriding Plasma nitriding, also known as ion nitriding, plasma ion nitriding or glow-discharge nitriding, is an industrial surface hardening treatment for metallic materials. This process is sometimes referred to as ion nitrocarburizing or plasma ferritic nitrocarburizing (FNC). Since plasma nitriding is normally performed at lower treatment temperatures, it is the heat treatment with the lowest risk of deformation. The process pressure will control the formation and uniformity of the plasma glow seam around the gear form. The process was developed in the 1920's as an alternative to the gas nitriding process.
