In plasma nitriding, the nitrogen is introduced into a vacuum chamber, ionized using an electric field (glow discharge), accelerated in the direction of the tool surface, and absorbed.
Areas of application
Automotive industry | Medical technology | Aerospace industry
Textile industry | Mechanical engineering | Tool making
Material groups
All steel qualities
Plasma nitriding heat treatments
- Plasma nitriding
- Plasma nitrocarburizing
- Improx® oxidizing (oxidizing in plasma)
- Combination of plasma nitriding or nitrocarburizing with oxidizing
Advantages
- A specific coating structure is possible (e.g. nitriding without the compound layer)
- An environmentally friendly process
- Partial nitriding is possible
- Increase in resistance to abrasive wear
- Less tendency to stick
- No adherence and better demolding
- Improved corrosion resistance in unalloyed and low-alloy steels
