Sintered parts can be plasma nitrided! In an Eltropuls treatment, an oil-removal process first takes place in the plasma nitriding plant, in which the calibration oil is also removed from the pores near the surface of the sintered part. The nitriding step can then start. Since in the plasma only the surface of the sintered component and not the pores opened toward the surface are nitrided, plasma nitrided sintered components are characterised by a high degree of dimensional stability and form retention – a major advantage over gas nitriding. Exceptional wear resistance is achieved!
