Diamond-like carbon (DLC) is any of seven forms of amorphous
carbon materials that display some of the unique properties of
films with very high hardness, high resistivity, and dielectric
optical properties, are now described as diamond-like carbon or
methods have been developed for producing diamond-like carbon
ion beam deposition of carbon ions (IBD)
deposition of carbon with or without bombardment by an intense
flux of ions (physical vapour deposition or PVD)
from an RF plasma, sustained in hydrocarbon gases, onto
substrates negatively biased (plasma assisted chemical vapour
deposition or PACVD).
variety of objects are now being coated, ranging from small
items, to large dies and moulds. The rapidly expanding uses of
the DLC films developed by the hybrid technique .
coatings may well find their biggest application in enhancing
properties of general wear parts.
Benefits include: Wear and
abrasion resistance , Low Friction , High Hardness ,
Anti-reflective Coating , Corrosion Resistance , Gas Barrier ,
Conformal Coating .
The world market for diamond, diamond-like, and CBN films
reached $473.5 million in 2006. This figure is expected to rise
to $530.8 million in 2007 and slightly over $1.0 billion by
2012, a CAGR of 14.3% between 2007 and 2012.
The use of
diamond-like carbon (DLC) coatings to improve the performance of
more complex mechanical components or systems is currently
