Nitrided + Coating Features
Base material hardness is rised to the vicinity of coating hardness by nitriding. So,the stress reduction at the interface of the base material and coating.

Continuous Nitrided + Coating process
Adhesion is improved to migrate to the coating in a clean surface state.
Cost reduction by the processing time is shortened.
