Stainless Steels: Plasma Nitriding vs Hard Chrome

Plasma nitriding creates a diffusion-based surface layer that enhances wear resistance, adhesion and corrosion protection without altering part geometry. Unlike hard chrome, which relies on a mechanical bond and requires line-of-sight for coverage, plasma nitriding delivers uniform treatment even on complex shapes. The process is clean, uses non-toxic gases, and maintains high reproducibility through recipe-controlled automation.
