PulsPlasma^® Nitriding Systems

These are vacuum furnaces for conducting plasma diffusion processes to enrich the component surface with nitrogen and/or carbon for increasing resistance to wear and corrosion. The PlaTeG PulsPlasma^® diffusion processes, especially PulsPlasma^® nitriding (PPN^TM) and PulsPlasma^® nitrocarburizing (PPNC^TM), are plasma diffusion processes that offer numerous advantages to customers over traditional nitriding processes such as salt bath nitrocarburizing or gas nitriding, as well as being environmentally friendly and making economical use of resources:

Low process gas and power consumption
Use environmentally friendly process gases
Flexible treatment temperatures ranging from 350 °C to 600 °C (high temperature up to 900°C)
Option of partial treatment using mechanical covers
Used to treat high-alloy and stainless steel (maintaining corrosion resistance)
Nitrided layer structure can be monitored
Used to treat sintered iron/steel as well as non-ferrous metals such as titanium and aluminum

PulsPlasma^® Generator Technology / The Latest Technology

The virtually square pulse form for pulsed current and voltage means that the necessary plasma output can be transferred quickly, optimally and almost losslessly to the components to be treated. Pulse and pause times can be programmed to anything between 30 µs and 999 µs. As a result, it is possible both to monitor the structure of the nitrided layer and to prevent the components from overheating.

For unipolar and/or bipolar operation
Arc suppression via rapid shutdown (< 0.1 µs)
PlaTeG PulsPlasma^® generators provide stable glow discharge plasmas even at room temperature
Optimized for PlaTeG-PPSA^TM technology for shorter treatment times and homogeneous results

Various PulsPlasma^® diffusion processes can be carried out depending on component load and the desired results of treatment:

PPN^TM—PulsPlasma^® nitriding—diffusion of nitrogen to increase resistance to wear and corrosion for most steels, titanium and aluminum

PPCN^TM—PulsPlasma^® nitrocarburizing—diffusion of nitrogen and carbon to increase resistance to wear and corrosion for steel

PPC^TM—PulsPlasma^® carburizing—diffusion of carbon to increase resistance to wear and corrosion for stainless steel

PPO^TM—PulsPlasma^® oxidizing—treatment to oxidize steel surfaces to increase corrosion resistance and reduce the coefficient of friction

LT-PPN^TM, LT-PPNC^TM, LT-PPC^TM of components made of steels with chromium contents > 13% to increase wear resistance while maintaining corrosion resistance

System Versions / Flexibility Means Reliable Processes
