An increase in the efficiency of gas-free impregnation of a porous carbon-graphite frame to aluminum alloys by applying thin electroplated metal alloying coatings to the surface of the pores of a carbon-graphite sample by electrochemical method is investigated. It is shown that the preliminary deposition of such coatings makes it possible to obtain alloying with highly pure elements, increasing the filling of pores with matrix melt at impregnation temperature (800 ° C).
