Nitriding and Nitrocarburizing

Nitriding and Nitrocarburizing are performed at lower temperatures than conventional heat treatments, which minimizes distortion. These heat treatments improve wear resistance, fatigue strength, and corrosion resistance. Nitriding/Nitrocarburizing Types: Ion Nitriding (Plasma Nitriding / Nitrocarburizing) Gas Nitriding (Gaseous Nitrocarburizing) Salt-Bath Nitriding (Liquid) Photo of … Continue reading
