IONIT Plasma nitriding and plasma nitrocarburizing


BALITHERM IONIT, the plasma nitriding and plasma nitrocarburizing process for sintered materials, all kind of steels (also high alloyed steels) and non-iron metals.

Plasma nitriding

This is an industrial surface hardening treatment for all kinds of steel. Under vacuum and through the application of a bias voltage, the Nitrogen and Hydrogen gas molecules become ionized and begin to react with the iron of the part to develop a hard nitrided zone (visible as glowing). This process is performed over a broad temperature range (350°C – 600°C) and in a vacuum environment. Process treatment takes place by diffusion and not by coating.

Plasma nitrocarburizing

Addition of carbon leads to the formation of hard, wear-resistant compound layers, as well as corrosion resistance even better than that of nitride steels. Nitrocarburizing also reduces reactivity with materials contacted by coated parts such, as lubricants (tribo-oxidation).
