COMPOSITE MATERIALS MANUFACTURING METHOD Russian patent published in 2015 - IPC B22F3/26 C22C1/04 

FIELD: metallurgy.

SUBSTANCE: porous workpiece is submerged into molten matrix alloy, it is subject to vacuum degassing, heating and overpressure exploration due to thermal expansion of molten metal in tank enclosed volume. As molten matrix alloy molten lead is used, and during heating the workpiece is additionally treated, then cooled and crystallised. Used tank consists of two chambers: A chamber for treatment and a chamber for pressure generation. At that porous workpiece is submerged into molten aluminium matrix alloy in treatment chamber and is heated to 100°C above temperature of aluminium alloy liquidus simultaneously with molten lead in chamber for pressure generation.

EFFECT: composite material has high conductivity, antifriction properties and resistance to corrosive environment.
