Effects of duplex pre-treatment on diamond deposition on pure titanium

The composite or graded interlayer combining titanium carbonitride and titanium nitride was prepared to improve the adhesion of diamond coating to Ti substrate. The compositional graded interlayer will enhance the chemical bonding between the substrate and diamond coating and provide a lower thermal...

Zusammenfassung:	The composite or graded interlayer combining titanium carbonitride and titanium nitride was prepared to improve the adhesion of diamond coating to Ti substrate. The compositional graded interlayer will enhance the chemical bonding between the substrate and diamond coating and provide a lower thermal stress. The diamond coating deposited directly on plasma nitride layer showed poor adhesion. A pre-carbonitrided interlayer improved the adhesion of diamond coating both on Ti substrate and the plasma nitrided layer.
