FIELD: metallurgy.
SUBSTANCE: first, steel plates are covered with a lead layer, then, they are filled with a water solution of flux, moisture is removed, after that, they are collected to packs and soaked in an aluminium melt at the overheat temperature that is by 50-100°C higher than the liquidus line of aluminium alloy.
EFFECT: reduction of surface tension of aluminium melt and improving flowability of aluinium along steel, which contributes to improvement of adhesion strength of composite material layers.
