Abstract

Aluminium brazing can only be achieved if pre-existing oxides are disrupted to allow molten filler metal wetting and flow between adjacent substrates to form a metallic bond. Mechanistic differences for various controlled atmosphere brazing processes are investigated and compared to previously described systems (vacuum, nickel, flux free). Mechanisms are predominantly surface feature controlled and therefore sensitive to surface changes. Brazing sheet clad with TRILLIUM™ composite is less susceptible to surface condition. Liberation of molten flux from within the composite acts at the metal-oxide interface disrupting the oxide, and AIDS filler flow by agitation thus promoting brazed joint formation.
