Hybrid Coating
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
Cross section metallographic structure of nitriding sample
Cross sectional hardness distribution of Nitriding sample
Comparison of scratch marks
Scratch marks of Nitrided + TiN
Scratch marks of TiN
