Surface Zone Modification by Atmospheric Plasma-Nitriding (APN) with the Aid of the Transmitted Plasma-Arc
Current research activities at the Institute of Materials Science of the Leibniz Universität Hannover are engaged with the development of a new nitriding-process. This process has the convenience that a nitridation of surfaces is possible under atmospheric conditions so that the device treatment may be performed fractional. With the aid of the transmitted plasma-arc, diffusion able nitrogen is applied at the workpiece surface. This atomic nitrogen diffuses into the device and constitutes special- and iron-nitrides which raises the abrasion- and corrosion resistance.
