Investigation of the processes of wetting of steel with aluminium in the production of laminated composites

Abstract

Experimental results show that high wetting forces of steel by aluminium in the formation of laminated composite materials by liquid phase impregnation are recorded in the activation of the surface with fluxes based on the eutectic of the KF–AlF₃ system and fluxes based on K₂TiF₆ and K₂ZrF₆. The bonding strength of aluminium with steel depends on the composition of the activating flux and the temperature of the formation process.
