Gas nitriding is a thermochemical surface hardening process without microstructure transformation at low temperatures of approx. 500 to 570 °C. Nitriding ensures hard surfaces and provides high resistance to wear, scratches and abrasion. In gas nitrocarburisation, the process is carried out in an additional carbon-producing atmosphere, whereby two layers ensure high wear resistance and corrosion protection. Our VT-N-OX® process provides additional corrosion protection through subsequent oxidation.
Compared to other hardening processes, the process operates at significantly lower temperatures, with noticeably reduced energy requirements. The absence of quenching in oil also makes nitriding a more environmentally friendly process.
