Plasma nitriding is a modern and environmentally-friendly nitriding process, adopted to steel quality and surface.

Process-technical features:

· Nitriding and nitro-carburizing of an alloyed steel, cast iron, sintered and special materials Reproducible, hard and ductile, nitriding layer structure

· Large treatment temperature range of 400 – 600°C

· Comparably short processing cycles

· Forced depassivation, also of high-alloy steels

· Partial nitriding of the workpieces

· Low distortion, high preservation of dimensional accuracy

· No high-cost mechanical post-treatment

· Furnace program coordinated to component parts

· Proven in individual and series parts

· Standing and/or suspended charging

· Environmentally-friendly

Process advantages:

Also component parts with complex geometry, bores or cylinders are provided with the plasma-nitriding type boundary layers. The process engineering of plasma nitriding in vacuum guarantees good dimensional stability and low distortion. Stress relieve annealing is especially useful before the mechanical finishing. With paste and solid coverings, workpieces can be plasma-nitrided partially. The vacuum processing saves the followings cleaning of the plasma nitrated charge. Roughness changes are so small that a mechanical after treatment can be dispensed with. Highly polished tools,which should be slightly finished after the processing, form ecceptions. Annealing sensitive steels and special materials can also be plasma nitrided above the usual treatment temperatures.
