Titanium carbonitride

Titanium Carbonitride coated VG-10 blade

Titanium carbonitride (TiCN) is harder than Titanium nitride (TiN) and it can be used without lubrication. Titanium Carbonitride is applied to machine tool cutters by vapor deposition. ^{[1] [2]}

Titanium carbonitride coatings have high hardness and wear resistance. Titanium carbonitride is a cermet—a composite of metal and ceramic. The ceramic provides high hardness, and the metal provides toughness. ^[3]

Titanium carbonitride can be prepared by reacting titanium dioxide and carbon in a furnace containing an inert gas, then reducing in nitrogen gas. ^[4]
