Profile: Nitriding Services specializes in surface treatment services. We offer gas processes, controlled gas nitriding (the nitregR process) and plasma processes. Plasma nitriding (also known as glow discharge or ion nitriding) is a low temperature, low distortion surface engineering process. A glow discharge plasma is used to transfer nitrogen to the surface of the components undergoing treatment. Operating at temperatures between 400°C and 600°C, these plasma processes can produce high surface hardnesses and penetrating to depths up to 0.8 mm.
