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.
Coating sectional model

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.
Hybrid(Nitrided + Coating) processing Step procedure
