Brazing method using patterned metallic film having high wettability with respect to low-wettability brazing metal between components to be bonded together

摘要

A method of brazing a plurality of components by heating the components superposed on each other with a brazing material interposed between adjacent bonding surfaces of the components, wherein the brazing material has a relatively low degree of wettability with respect to the material of the components to be brazed, and is applied to a patterned film of a high-wettability metal having a relatively high degree of wettability with respect to the brazing material, which film is formed on at least one of bonding surfaces of the components, so as to cover predetermined areas of the bonding surface while leaving adjacent non- bonding areas of the bonding surface uncovered so as to restrict the flow of brazing material.
