material : High Speed Steel SKH57 Roughness of the surface processing before 0.8S

Change of coating hardness by tempreture

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

Adhesion is improved to migrate to the coating in a clean surface state.
Cost reduction by the processing time is shortened.
