The Ion (Plasma) Nitriding Process
The ion nitriding process is carried out in a vacuum vessel where a high-voltage electrical charge forms plasma, causing nitrogen ions to accelerate and impinge on the metal. When the nitrogen ions bombard the part they heat up the metal, clean the surface, and absorb nitrogen into the surface. This process is sometimes referred to as ion nitrocarburizing or plasma ferritic nitrocarburizing (FNC).
