Vacuum brazing of carbon nanotube bundles

Materials Letters, 2008
Abstract We have investigated vacuum brazing of CNTs with a eutectic alloy (Ag x Cu y ) doped with Ti. Bonding is confirmed to involve formation of covalent bonds between Ti and C atoms. The brazing in vacuum leads to the interdiffusion of Ti and C atoms and reaction at the joining interfaces.

Brazing Aluminum in Low Vacuum

2019
The technology of vacuum brazing components of aluminium and its alloys requires a high vacuum (residual pressure p0 = 10"2–103 Pa) and the introduction of an evaporation getter – magnesium. This requires expensive special equipment with a relatively low productivity even in the presence of multi-chamber continuous furnaces.

Thermal modelling of a brazing process of vacuum interrupters

2016 27th International Symposium on Discharges and Electrical Insulation in Vacuum (ISDEIV), 2016
This work describes a three-dimensional thermal finite-difference analysis of a brazing process of Vacuum Interrupters. The overall objective is to develop a reliable numerical model to be used to optimise the number of interrupters and the configuration in which these are placed within the furnace so that the process duration and cost are minimized ...

Joining of alumina by vacuum brazing

1993
The joinability of alumina to titanium and Ni-superalloys has been studied by wetting expts., nondestructive testing (NDT), and shear strength measurements. The spreading of the braze is affected not only by the surface conditions of mating materials but also by the type of brazing alloy.
