FIELD: technological processes.
SUBSTANCE: invention relates to production of carbon-graphite composite material. Method includes vacuum degassing of porous carbon-graphite workpiece, its impregnation in impregnation chamber by molten matrix alloy under effect of excessive pressure due to thermal expansion of lead melt in pressure chamber at heating by 100 °C is higher than liquidus temperature of matrix alloy simultaneously with lead melt. Antimony alloy is used as matrix 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.
