Thermionic Vacuum Arc

The TVA system is regarded as one of the plasma-based coating systems in the literature. In this system, the coating material is exposed to electron bombardment with the electron gun.
        With this method, the coating process by forming an anode material plasma is performed in the high vacuum (10^-6 torr). Due to the high vacuum, the TVA system can be very quickly performed the process of forming high-purity thin films.

Advantages of TVA system;

• It is completely environmentally friendly coating system.
• There is no need to use any gas to coating.
• Since the coating is carried out at high vacuum values and without using any gas, high purity products are come out.
• It is possible to coat with the use of suitable holders on the products of all desired shapes.
• Suitable for ceramic and metal surfaces.
• There is no thermal expansion problem in the coating of metals since high temperature does not occur during the coating process.
• Ideal coating system for samples made with precise measurements.
• There is no need to heat the material in the ceramic coating in order to provide adhesion to the material.
• No special processes are required for the coating process.
• The coating process takes place rapidly.

In our company, the Thermionic Vacuum Arc system is produced and designed for intended production and needs.
