Vacuum Brazing Ceramics

Due to its great flexibility and universality the brazing of metals and ceramics has been established as a very widely used standard procedure.

Vacuum brazing ceramics.

The brazing of a metal and ceramic has been established in particular in electrical engineering. 27 years of continuous improvement has enabled us to build our furnace brazing and contract manufacturing operations into a reliable framework of turnkey services and products you can depend on. An article on advanced microwave brazing was published 2 in issue 161 of practical welding letter for january 2017. A typical interfacial structure of joints.

Vacuum brazing is particularly advantages for joining ceramics using active braze fillers which have active elements such as ti hf zr and v added to react with ceramics for form a chemical bond at temperature is high vacuum environments. Ceramic to metal brazing components are widely used in electrical engineering due to their good performance for high vacuum high voltage and high pressure applications we manufacture a large range of metalized ceramic components with the latest technologies in order to meet the needs of our clients. By means of brazing vacuum tight and thermally stable compounds with high strengths can be produced. But there are many limitations in joining this duo of materials that range from their structures nature of bonding physical properties to a complex phenomenon like wetting spreading and adhesion.

In this study the carbon fiber reinforced zrb 2 sic composite ceramic was joined to ti6al4v alloy with ag cu eutectic alloy filler at varied holding time and a fixed temperature of 800 interface microstructure and shear strength of brazing joints were studied. Extensive experience in materials joining enables vpe to customize our vacuum brazing services and ensure the best process conditions for your assembly application. Is a joining process between a metal and another metal or metal s to a ceramic that offers significant advantages which include extremely clean superior braze joints of high integrity and strength. The brazed zsc f ceramics agcu tc4 alloy is endowed with good metallurgical bondings.

We have identified particular processes to overcome the many known difficulties involved in the forming of ceramic joints. Ceramic to metal joining has its potential applications in microelectronics packaging metal ceramic seals vacuum tubes sapphire metal windows etc. Our passion is the pursuit of innovative engineering advanced material joining and turnkey solutions where vacuum or furnace brazing technology is. Davis scientific treatments has been developing the vacuum brazing of ceramic components in many special applications.
