Plasma nitriding

Partial nitriding prevention is also okay. It is nitriding powered by clean and eco-friendly electricity.

"Plasma nitriding treatment" is a method that utilizes glow discharge to ionize a small amount of mixed gas of N2 and H2 introduced into the furnace, and nitrides the treated items with the ionized N ions. A compound layer of iron nitrides is formed on the product surface, enhancing wear resistance, fatigue strength, and corrosion resistance. Furthermore, if sputtering is performed to collide H ions with the product surface before nitriding to clean nitriding inhibitors, nitriding can be achieved even for steel types that cannot undergo conventional ammonia gas nitriding due to strong passive films like stainless steel. The greatest advantage compared to other nitriding methods is the ability to partially cover the treated items with fixtures and block the glow discharge, allowing for localized prevention of nitriding. [Characteristics (partial)] ■ Applicable steel types: all iron-based metals ■ The ions clean the surface, suppressing the formation of surface embrittlement layers, resulting in a smooth finish that eliminates the need for post-processing. ■ A wide range of nitriding temperatures can be selected according to the application of the product, and processing at low temperatures minimizes thermal distortion. *For more details, please download the PDF or feel free to contact us.
