carbonitride (Ti(C,N)) and alumina (Al0) can be made.CVD-coated grades are suitable for
wear resistance in demanding applications with high feed rates and intermediate to high
Most modern grades are coated with either CVD (Chemical Vapour Deposition) or PVD
With CVD-technique layers of titanium carbide (TiC), titanium nitride (TiN), titanium
grades are recommended for applications with low feed rate where high edge toughness
is required. PVD-coated grades are suitable for applications with low to intermediate
The common coating materials made by PVD-technique are titanium nitride (TiN),
titanium carbonitride (Ti(C,N)) and titanium alu-minium nitride ((Ti,AL)N). PVD-coated
be added. Tungsten carbide is the main component and gives the hardness. Cobalt is
like tantalum carbide (TaC),titanium car-bide (TiC) and niobium carbide (NbC) can also
Cemented carbide is an alloy of tungsten carbide (WC) and cobalt (Co). Cubic carbides
the binder phase and gives the toughness. Cubic carbides are added in order to affect
