brazing a joint formed by at least two aluminum alloy components with an aluminum braze alloy;
applying a slurry comprising at least one of magnesium, calcium, and a lanthanide series metal and mixtures thereof to said braze joint to form a coating thereon; and
allowing said coating to dry, said coating functions to form a passivating coating on said braze joint under corrosive conditions.
10. An aluminum alloy heat exchanger comprising a plurality of tubes and manifolds interconnected to form an enclosed flow path with said interconnections being sealed with an aluminum base braze alloy with said braze alloy further comprising at least one of magnesium, calcium, and a lanthanide series metal and mixtures thereof in an amount sufficient to form a passivating film under corrosive conditions.
