FIELD: technological processes.
SUBSTANCE: invention relates to production of carbon-graphite composite material. Method includes vacuum degassing of porous carbon-graphite workpiece, its impregnation with melt of matrix aluminum alloy under action of excessive pressure due to thermal expansion of melt at heating above temperature of liquidus of aluminum alloy. Degassing is carried out before immersion of porous workpiece into melt of matrix alloy, and before impregnation two-layer galvanic coating consisting of internal copper and external palladium layers is applied on porous workpiece.
EFFECT: higher quality of composite material.
