Technology

The application of coatings in vacuum medium by ion-plasma technologies, known as PVD methods, can be summarised as follows.

The generated titanium vapours in plasma state (with 90% ionisation) and high density of the metal plasma secures the establishment of several types of chemical and physical bonds with the atomic lattice of the processed basic material at the stage of “deep energy levels”.

This process secures a considerable speed of the coating growth, equal spread of thickness, as well as excellent adhesion (cohesion between the coating and the coated material).

The coating made by the PVD methods possesses several advantages over the other known methods:

- the technological process and the products are absolutely harmless both to people and the environment in comparison with galvanic, galvanic-plastic and thermal methods for application of coatings.

- the adhesion between the coating and the base material is ten (10) times stronger than the one in galvanic methods.

- the coating with thickness of five (5) microns is absolutely resistant to temperatures from -40°C to +80°C, as well as to acid rains and hailstorms.

- high wear resistance is provided (from two to four times) to chemical-abrasive wear, as well as considerable reduction in heat loads of the metal-cutting equipment.

- the colour retention of the coating under atmospheric conditions is guaranteed for the period of 50 years (this concerns domes of churches, temples, mosques and other buildings).

- high heat- and light-reflection is achieved (up to 80-85%), something which is very important for countries with hot climate.

Application

- in construction and architecture:
- the making of domes for churches, mosques and other buildings
- decorations on products made of porcelain, ceramics, glass, granite, etc.

- in industry:
- for providing longer exploitation of metal-cutting and metal-processing equipment
- for protection of items exposed in aggressive medium

- in art:
- coatings on faience, ceramics, terracotta, granite
- coatings on church plates

- in dentistry:
- coatings on crowns, dentures, etc.
