Nitriding without White Layer (Compound Layer)
Composition and characteristics
- Thermo-chemical process to enrich the case of a component or work piece with nitrogen
- Due to the low activity of nitrogen in the atmosphere only a precipitation zone is formed.
- The formation of a white layer is suppressed.
- Enables a clear raise of the endurance limit, by evoking internal compressive stress in the ductile case.
Fields of Application
