Abstract

PURPOSE: To facilitate brazing and prevent lack of braze run by increasing the heat absorption of a member of a smaller surface area per unit weight out of brazing members in vacuum brazing for articles consisting of metals of high reflectivity on surfaces.
CONSTITUTION: If there is a difference in surface area per unit weight between target parts in the case of performing vacuum brazing of articles consisting of metals of high reflectivity on surfaces such as aluminum and its alloy or stainless steel, blackening treatment which does not hamper vacuum brazing is applied on the surfaces of the parts of a smaller surface area per unit weight and vacuum brazing is accomplished. If the parts are of a stainless steel material, known means such as a chromic acid oxidation method, a sulfide staining method, and acidic blackening oxidation method are used and if the parts are of aluminum, arbitrary means such as an anodic oxidation method are used. Thereby, the uniform brazing temp. is attained in spite of existence of a difference in surface area per unit weight between the target articles.
