METHOD OF MANUFACTURING LAYERED METAL MATERIALS Russian patent published in 1999 - IPC

FIELD: composites. SUBSTANCE: invention, in particular, relates to manufacturing layered metallic materials, preferably on steel base. Method includes modifying content surfaces of layers of blank. Surface of base, made from harder metal, is treated by electrolyte-plasma method preceded by cleaning under constant current conditions and subsequent strengthening under pulse current conditions. Surface of plating layer is treated to create roughness. Laying base and plating layer is effected simultaneously with assembling blank and sealing joining zone. Blank is then subjected to high-speed heating and integrated rolling. EFFECT: strengthened joint of plating layer with base. 3 cl, 3 dwg, 1 tbl
