METHOD OF PRODUCING COMPOSITE STEEL-ALUMINIUM COMPOSITES Russian patent published in 2014 - IPC B32B15/01

Abstract RU 2530129 C2

FIELD: process engineering.

SUBSTANCE: invention relates to production of cylindrical composite steel-aluminium materials. Cylindrical steel article with thread is pre-coated with flux containing KF 55% (mol.) and AlF₃ 45% (mol.) and impregnated in aluminium melt with overheating temperature 50-100°C higher than aluminium alloy liquidus line. Note here that thread pitch 0.3 mm is selected to allow a capillary filling of said thread with aluminium melt.

EFFECT: simplified and high-efficiency process.
