Abstract
The process of forming a composite material carbon - graphite-aluminum alloy by impregnation of a porous frame AG-1500 is studied. The technology of filling the open porosity of carbon graphite with a metal melt in a device for impregnation in the mode of constant heating of the furnace is described. The method of applying a protective coating to the inner surface of the pores is shown. It is possible to seal the matrix alloy AK12 in the pores of AG-1500 with lead. It is shown that such processing allows to compact the aluminum alloy and modify it due to the comprehensive pressure of the lead alloy.
