METHOD FOR MAKING SOLDERED HONEYCOMB MEMBER WITH USE OF LAMINATE-STRUCTURE METALLIC SHEETS

摘要

manufacture of members used as catalytic neutralizers of exhaust gases of transport vehicles. SUBSTANCE: metallic sheets have structure with locally arranged ducts for passing fluid. Several sheets are made of laminate material. At least one layer is made of chrome containing steel and at least one layer is made, mainly of aluminium. At soldering process heat treatment is realized for homogenization of said layers at first in vacuum or in reduction atmosphere and then in oxidation atmosphere. Used solder is nickel-base material containing 0.5-0.8 mass% of boron. EFFECT: increased corrosion resistance and mechanical load strength of honeycomb members. 5 cl, 5 dwg
