Cladding of powder composition by a metal melt. Free and forced impregnation

The report presents technological schemes of free and forced filling of pores of a powder composition by a metal melt. An example of testing the proposed schemes was impregnation of the powder composition «B-Al-W» with the aluminum melt. Forced impregnation was carried out by the action of a pulsed magnetic field on the melt. Experimentally, with the help of metallographic research, the boundary of penetration of the melt into the pores of the powder depending on the magnitude of the force action on the melt was established. The feasibility of the developed method of cladding of the powder by the metal melt is confirmed and the directions of further systemic research in the development of new technologies are determined.
