Natural diamond has long been coveted for its extreme properties. In
thin film form, however, capturing these properties reliably and
economically has been in general a disappointment—until now. Thin film diamond has graduated from the laboratory
to become a genuine industrial material whose properties and performance
characteristics can be characterized and reproduced. What
is not widely understood is that the properties of these films
can be tuned over a very broad range. Thus, like steel or aluminum
alloys which are optimized for particular applications, so too
can the properties of thin film diamond be adjusted in a controllable
and reproducible manner.

UNCD®
(for ultrananocrystalline diamond) developed by ADT allows for
the realization of many different types of diamond films
that capture different subsets of properties of diamond, allowing
ADT the unique ability to tailor UNCD for a broad range of applications.
For instance, rough diamond films that have been available for
years are extremely abrasive, and thus useful for cutting applications.
However, UNCD allows for the roughness of the films to be controllably
varied enabling films that are extremely smooth and exhibit very
low friction yet retain the extreme wear resistance of
natural diamond. In a similar manner the thermal conductivity,
electrical conductivity, and optical properties can be varied
over many orders of magnitude. Thus films that are highly electrically
conducting at room temperature can have either high or low thermal
conductivity and can also be made optically more or less transparent.
ADT’s UNCD Aqua Series™ is the first
family of diamond thin films to be brought to the marketplace
that spans a range of film properties that makes each one suitable
to a particular application. All of the UNCD Aqua varieties are
smooth enough to exhibit low friction in most applications, yet
vary considerably in thermal conductivity, electrical conductivity,
and optical transparency.
