Insert grades HighCutting speedLo w CermetCVD CoatedMEGACOAT NANO CermetCermet Hardness (GPa) Insert grades A Cermet Cermet KYOCERA is known as one of the leading manufacturer of cermets. Cermets combine toughness with superior wear resistance, and provide longer tool life and excellent surface finishes. Typical materials used in cermets are TiC, TiN, TiCN and NbC. PVD coated cermet (MEGACOAT / MEGACOAT NANO Cermet) PVD coated cermet is coated on cermet substrate with a thin layer of high wear resistance and high adhesion resistance by PVD (Physical Vapor Deposition) technology. Generally because of the low processing temperature of PVD compared with CVD, PVD coated cermet features less deterioration and more bending strength.
