How does Plasma Nitriding work?

The process begins with loading parts in a vacuum chamber. Nitrogen and hydrogen are ionized to form active species. Nitrogen ions bombard the surface, forming nitride compounds while controlling layer depth and hardness.

• Vacuum chamber ensures controlled environment

• Gas ionization generates reactive nitrogen species

• Nitrogen diffusion produces FeN, then Fe₃N and Fe₄N

• Process parameters control hardness, thickness, and reproducibility
