| 摘要 |
The present invention is directed to a process for preparing substrates, such as aluminum and aluminum alloy surfaces in heat exchangers, for brazing by depositing thereon a kinetic sprayed brazing composition. The process simultaneously deposits composite particles that include all braze materials, i.e., both filler alloy and brazing flux, and corrosion protection materials used in the brazing of aluminum fins to plates and tubes in a single stage.
