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 aluminum alloy matrix under effect of excessive pressure due to thermal expansion of melt at heating above liquidus temperature of aluminum alloy. Degassing is performed before immersion of porous workpiece into melt of matrix alloy, and before impregnation a four-layer galvanic coating consisting of internal copper, intermediate chromium and silver, and external nickel layers is applied on the porous workpiece.
EFFECT: higher quality of composite material.
