NN IMZ-01-02. A sample of a metal-ceramic high-voltage hermetic conduit made by contact-reactive soldering in a vacuum

TRL-6

Ceramic vacuum seals are intended for use in mechanical engineering, energy, aerospace industry, instrument making and other industries

Market and economic attractiveness

• The proposed Typical technology for the production of metal-ceramic assemblies of hermetic guides for electron beam guns in welding and spraying installations has successfully passed the test and manufactured products
• The optimized design of metal-ceramic assemblies of hermetic conductors obtained by contact-reactive soldering technology allows to obtain products with increased thickness of current leads , which ensures increased rigidity of assemblies during operation in comparison with foreign analogues
• The operating experience of the manufactured units has shown their high reliability under thermal cycling conditions
• The developed technology has a lower cost of products by 50% compared to imported counterparts and a greater resource.

The main advantages (strengths) of the development

• The developed technology of contact-reactive soldering eliminates the need for a previous time-consuming and energy-consuming operation of metallization of ceramics (metallization of ceramics is carried out with a paste at a temperature of up to 1600 °C) with the provision of high-quality wetting of the surface of ceramic blanks with solder melt, which is formed as a result of contact-reactive interaction of its components
