Ion
Plating (PVD) is a highly specialized, environmentally
friendly vacuum coating process.
-
Material
to be coated is physically removed from a source
in vacuum by evaporation.
-
The
evaporated material is transported in the form of energetic
vapor and forms a film after condensation on the substrate.
-
Ion
plated coatings are applied on various substrates
such as Stainless Steel, Nickel plated brass articles
to improve their corrosion resistance and wear
resistance.
-
These
coatings are durable, cost effective alternative
to traditional electroplated coatings.
-
The
coating process is 100% environmentally friendly
and the coatings are ultra hard, resist cracking,
chipping and maintain their finish under daily
wear and tear.
-
Ion
plated decorative coatings have superior performance
over conventional electroplated coatings in all
decorative applications.
-
Ion
plated (PVD) multi-layer coating of titanium nitride
(TiN) and gold is applied on decorative products,
where the inherent wear resistance properties
of titanium nitride coating combined with its
golden colour is advantageously used to improve
the quality of products. The amount of gold used
is much lower compared to electroplated gold items,
thus making the process economically attractive.
-
It
is possible to obtain various tones of golden
color using PVD method by varying the reactive
gas contents. The durability of PVD TiN coatings
and the controllability in obtaining the required
golden tone are the most attractive aspects of
this process.
-
TiN
is a hard coating having hardness of greater than
80 HRC, which is approximately few times harder
than the typical high speed steel. TiN provides
resistance to chemical corrosion because of it's
chemical inertness.
