Abstract

The possibility of increasing the filling degree of open pores with aluminum melt during the impregnation of carbon-graphite material by applying metal-galvanic film coatings to its surface is investigated. Two types of electroplating coatings are used - nickel and combined coating consisting of copper and cadmium layers. Impregnation of the coated samples was carried out using autoclave-free technology in a special impregnation chamber. It is shown, that metal-galvanic coatings contribute to a lighter flow of aluminum melt into the pore cavity, providing a full-fledged impregnation of carbon-graphite material with a matrix alloy at reduced temperature (≤ 900°C) and pressure (3-5MPa).
