Is Ion (Plasma) Nitriding different than Ion Nitrocarburizing (FNC)?

What is the difference between Ion Nitriding and Ion Nitrocarburizing (Ferritic Nitrocarburizing--FNC)?

UltraGlow® Ion Nitriding (also known as Pulse Plasma Ion Nitriding) is widely used in manufacturing because of its numerous advantages. The use of UltraGlow® Ion Nitriding in various industries, including automotive, agricultural, military, aerospace, energy, and off-highway equipment, to name a few, has shown great potential for solving problems related to design, production, and material.

What is UltraGlow® Ion (Pulse Plasma) Nitriding?

UltraGlow® Ion (Pulse Plasma) Nitriding is a case-hardening treatment carried out in a vacuum vessel where a high-voltage electrical charge forms plasma, causing nitrogen ions to accelerate and impinge on the applicable material. When the nitrogen ions bombard the part, they heat up the metal, clean the surface, and diffuse nitrogen into the surface. Treatment periods may vary from a few hours up to 60+ hours for special applications while temperatures will range from 750°F to 1100°F for ferrous alloys.

What is UltraGlow® Ion Nitrocarburizing (Ferritic Nitrocarburizing-FNC)?

Ion Nitrocarburizing (Ferritic Nitrocarburizing) is essentially the UltraGlow® Ion Nitriding process performed in a mixture of nitrogen and hydrogen with small additions of gases containing carbon. In this thermochemical treatment, both nitrogen and carbon are diffused into the surface of ferrous materials usually at temperatures not exceeding 1100°F.
