Plasma nitriding, also known as ion nitriding or glow-discharge nitriding, is a state-of-the-art thermochemical case-hardening process. By introducing nitrogen ions into the surface of a metal component within a high-voltage vacuum chamber, we create a highly durable, wear-resistant casing.
Unlike traditional liquid or gas nitriding, the plasma process allows for independent control of temperature and nitrogen potential. This results in precise metallurgical tailoring, zero toxic byproducts, and the lowest possible thermal distortion available in the industry today.
Our Plasma Processes:
- Plasma Nitriding: A thermo-chemical diffusion process that enriches the surface with nitrogen to improve hardness, wear resistance, fatigue strength, and component life while maintaining dimensional accuracy.
- Plasma Nitriding + PLASOX® (Post Oxidation):Combines Plasma Nitriding with an advanced post-oxidation treatment to produce a dense black oxide layer, significantly improving corrosion resistance, reducing friction, and enhancing surface appearance.
- Plasma Nitrocarburizing: A controlled plasma diffusion process that introduces both nitrogen and carbon into the surface, providing excellent wear resistance, improved sliding properties, reduced friction, and increased fatigue strength.
- Plasma Nitrocarburizing + PLASOX® : An advanced duplex treatment combining Plasma Nitrocarburizing with PLASOX® post-oxidation for maximum wear resistance, excellent corrosion protection, superior anti-scuffing properties, and an attractive black finish.
