DLC COATING

DLC coating (diamond like carbon) is a surface finish applied to the solid tungsten carbide cutter body by Plasma Enhanced Chemical Vapour Deposition (PE-CVD) under vacuum and at low temperature.

The PE-CVD applied coating of hybridized carbon, SP2 graphite and SP3 diamond, gives a harder surface coat with a lower friction co-efficient, leading to a tool life which is typically 2-3 times that of untreated STC.

Deposition temperature 170 °C
Maximum usage temperature 250 °C
Thickness µ 1-3
