Vacuum Brazing Ceramics

An article on amorphous filler metal for vacuum brazing ceramics to titanium was published 4 in issue 136 of practical welding letter for december 2014.

Vacuum brazing ceramics. 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. A typical interfacial structure of joints. Davis scientific treatments has been developing the vacuum brazing of ceramic components in many special applications. Extensive experience in materials joining enables vpe to customize our vacuum brazing services and ensure the best process conditions for your assembly application.

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. Vacuum brazing is a precision brazing technique used to join critical assemblies many of which employ delicate or intricate features. Ceramic to metal joining has its potential applications in microelectronics packaging metal ceramic seals vacuum tubes sapphire metal windows etc. 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 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. An article on advanced microwave brazing was published 2 in issue 161 of practical welding letter for january 2017. Vacuum brazing of ceramics. 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. The brazing of a metal and ceramic has been established in particular in electrical engineering. Our passion is the pursuit of innovative engineering advanced material joining and turnkey solutions where vacuum or furnace brazing technology is. 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.

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.
