PACVD Coating Technology

PACVD coating is the abbreviation of Plasma Assisted Chemical Vapour Deposition.

What is PACVD Coating Technology?
PACVD coating is the abbreviation of Plasma Assisted Chemical Vapour Deposition.

PECVD Coating Technology
The term PECVD coating is also used; E for Enhanced. Whereas in a PVD coating process the materials are evaporated from a solid form, in PACVD the coating results from a gas phase. In order to build carbon (diamond) coatings, acetylene (C2H2) or for silicium-containing coatings HMDSO (hexa-methyl-disiloxan) can be added. These gasses can be cracked in the plasma to become available for the coating.

DLC coating
An example of a PACVD coating is DLC coating (Diamond Like Carbon). It is used as a tribological coating, e.g. as an engine-coating for automotive components to make the component wear resistant and achieve friction reduction. Or it can be used as a tool coating, due to its anti-sticking properties very suitable for the machining of cast and wrought aluminium and plastic injection moulds.
