Corrosion-resistant and brazeable aluminum material and a method of producing same.

摘要

A corrosion-resistant and brazeable aluminum material has an aluminum core, and a thermally sprayed layer formed on the core is composed of a brazing metal intermingled with zinc or its alloy. The brazing metal may be a mixture of aluminum and silicon, an aluminum-silicon alloy, a blend of the mixture with the alloy, or silicon. The brazeable aluminum material may be produced by blending a first powder of the brazing metal with a second powder of a corrosion resistant substance including zinc, so as to prepare a powder mixture, and then thermally spraying the powder mixture onto the aluminum core.
