  • VACUUM BRAZING - CERN
    Vacuum brazing is favorable for: Clean UHV-components, large joint surfaces, precise assemblies of high quality, readily oxidizing active base materials (Ti, Nb, )
  • 02490_BR_BT_Grundlage_Loeten_EN_MON4_210x279 - Umicore brasage
    While flux and gases may become trapped in brazing gaps when brazing in atmosphere, this is virtually never the case when brazing in a vacuum, thus re-sulting in brazed joints with a good de-gree of filling and high strength
  • Study on element diffusion behaviour of vacuum-furnace brazing 316 L . . .
    The brazing temperature have a great influence on the diffusion behaviour of the elements Si, Fe and Ni The diffusion coefficient values at different positions in brazed joints can be accurately calculated by the proposed model
  • Vacuum Brazing - Indico
    For brazing with Ag-based filler materials, a diffusion layer has to be applied This can be achieved by certain combinations of electroplated copper (H2-diffusion) and nickel (barrier for Ag)
  • Issues in Vacuum Brazing - SECO WARWICK
    The purity level of the atmosphere (vacuum) can be precisely controlled Atmospheres of much higher purity can be achieved than can be obtained in regular atmosphere furnace, in effect; there is less residual oxygen to contaminate the work piece
  • Diffusion Brazing
    Diffusion brazing provides a means to fill joints that are not perfectly smooth or flat (a fea-ture of liquid-phase joining), while offering greater flexibility with regard to joint configu-rations and mechanical properties than can be obtained from diffusion bonding
  • Diffusion and microstructure analysis of copper vacuum brazing with Cu . . .
    Cu-P based filler was carried out by studying effects of diffusion treatment after vacuum brazing using a tube-sheet joint, and the influence of diffusion treatment on brazing joint was investigated by means of electron microscope, energy spectrum analysis and tensile force test
  • Brazing of Porous Nickel to Copper and Stainless Steel: Microstructure . . .
    A brazed joint of Cu Porous Ni SS304 with VZ2250 and MBF67 brazing filler metal was prepared in a high vacuum furnace at different brazing times of 5, 10, and 15 minutes for 1015 °C with a heating and cooling rate of 10 °C min, respectively for comparison purpose
