Plasma Nitriding in general is a heat treating that is used to case harden surfaces using nitrogen. This process is mostly used on materials such as low-carbon, low-alloy steels and other medium and high carbon steels. Products produced from this process include gears, crankshaft, molds, forging tools and dies.
Nitriding offers many advantages where high temperature and dangerous chemicals are avoided. The process uses an ionized gas with intense electric field. The gases we use are typically environmentally safe.
PVA TePla PulsPlasma® Nitriding equipment offers several key advantages over our competitor’s systems in the area of performance and costs.

PVA TePla- vacuum furnace producer from Germany: These are vacuum furnaces for conducting plasma diffusion processes to enrich the component surface with nitrogen and/or carbon for the purpose of increasing resistance to wear and corrosion. The PlaTeG PulsPlasma® diffusion processes, especially PulsPlasma® nitriding (PPN) and PulsPlasma® nitrocarburizing (PPNCTM), are plasma diffusion methods 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 – 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
