Pulse Plasma Nitriding

PulsPlasma® nitriding (PPN) is an advanced thermochemical heat treatment that creates highly wear- and corrosion-resistant nitride layers on steel surfaces. Utilizing a pulsed direct-current glow discharge, PPN efficiently splits environmentally friendly gas mixtures—primarily nitrogen, hydrogen, and methane—under vacuum conditions. This innovative process stands out for its low gas consumption, minimal emissions, and the complete avoidance of harmful by-products, making it both eco-friendly and cost-effective.

PPN technology allows precise control over the structure and properties of the nitride layers. By adjusting key process parameters—such as gas composition, temperature, duration, pressure, and voltage—the treatment can be tailored to meet the specific functional and operational requirements of each component.

The process

Nitriding is a heat treatment process for enriching component surfaces with nitrogen atoms. The simultaneous use of nitrogen and carbon atoms is known as nitrocarburizing. Nitriding and nitrocarburizing can be used to create extremely hard steel surfaces. Most applications require no post-treatment, ensuring a streamlined and sustainable solution for modern surface engineering needs.
