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.
An article on advanced microwave brazing was published 2 in issue 161 of practical welding letter for january 2017.
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.
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.
The brazed zsc f ceramics agcu tc4 alloy is endowed with good metallurgical bondings.
Due to its great flexibility and universality the brazing of metals and ceramics has been established as a very widely used standard procedure.
Davis scientific treatments has been developing the vacuum brazing of ceramic components in many special applications.
Vacuum brazing is a precision brazing technique used to join critical assemblies many of which employ delicate or intricate features.
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.
By means of brazing vacuum tight and thermally stable compounds with high strengths can be produced.
The brazing of a metal and ceramic has been established in particular in electrical engineering.
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 joining has its potential applications in microelectronics packaging metal ceramic seals vacuum tubes sapphire metal windows etc.
A typical interfacial structure of joints.
