METHOD OF MAKING LAMINAR COMPOSITE MATERIALS Russian patent published in 2014 - IPC B32B15/01 B23K20/16 B32B38/08

Abstract RU 2534908 C1

FIELD: metallurgy.

SUBSTANCE: invention relates to production of laminar composite steel-aluminium materials. Steel sheets are pre-coated with flux water solution containing KF - 36-40%; AlF₃ - 44-50%; K₂TiF₆ - 10-20%, water is removed to pile the sheets to be impregnated with aluminium melt with overheating temperature some 50-100°C higher than aluminium melt liquidus line.

EFFECT: better adhesion between aluminium and steel, titanium alloyed transition intermetallide ply their between.
