Ion-Plasma
(vacuum) technology
|
Ion-plasma
technology is used for applying film coatings of metals, alloys
and their compounds - oxides, nitrides and carbides.
This technique uses ion and plasma beams that allow the formation
of high-quality reinforced, protective, wear-resistant
and decorative coatings on practically any types of
surfaces and materials.
Key
features

|
An
important feature of these technologies is their high efficiency
and low specific power consumption (1 - 5 kWh/m²) in comparison
with other methods, e.g. magnetron. Ion-plasma technologies utilise ionic
assistance and do not require heating of work surface (working
temperature range 30-100°C). It makes possible to apply coatings on
plastic parts and thermally treated metals without deterioration of their
properties.

These technologies are commercially used in the production of:
- architectural
and heat-shielding glasses with up to 70%-reflection in infra-red
range
- high
sharpness mirrors with selective factor of reflection (anti-dazzle
mirrors for automobiles)
- decorative
coatings
The
current equipment can be adapted to specific needs. New equipment can
also be designed and developed for special requirements.
Research
is now being conducted in the fields of development of new coatings
such as sensory, radio engineering, electrographic and other applications.
