CVD diamond on hard metals

Adherent CVD Diamond layers on hard metals are possible with titanium-boron-nitride intermediate layers. The diamond layer thickness can be higher than 100 µm. The removal of the cobalt binding phase via etching is no longer necessary, which improves the mechanical strength in the intermediate zone.   Examples:

• Piston rings and ball bearings made of hard metals
• Hard metal tools
• Hard metal erosion protection components
