METHOD FOR PRODUCING CARBON-GRAPHITE COMPOSITE MATERIAL Russian patent published in 2021 - IPC B22F3/26 C22C1/08 

Abstract RU 2751873 C1

FIELD: metallurgy.

SUBSTANCE: invention relates to the field of metallurgy, namely to the creation of composite materials by impregnating a porous frame. A method for producing a carbon-graphite composite material includes vacuum degassing of a porous carbon-graphite workpiece in an electrolyte solution. Electroplated coating is applied to the workpiece. The workpiece is impregnated in the impregnation chamber with a melt of a copper-phosphorous alloy matrix under the influence of excessive pressure due to thermal expansion of the lead melt in the pressure chamber when heated by 100°C above the liquidus temperature of the matrix alloy simultaneously with the lead melt. Vacuum degassing is carried out in a nickel electrolyte solution containing 140 g/l of nickel sulfate, 50 g/l of sodium sulfate, 30 g/l of magnesium sulfate, 20 g/l of dry boric acid. Electroplating is made of sequentially deposited inner nickel, intermediate zinc and silver, and outer copper layers.

EFFECT: composite materials quality improvement.
