Sažetak
The mechanism of interaction of the cast iron melt with the layer of nanodispersed compound includes the following processes: heating of the layer of powder (possibly paste) due to the physical heat of the melt ; fi ltration of the melt into the pores of the powder and its further heating ; distribution of nanopowder particles in the liquid phase at the time of melt fi ltration ; further distribution of nanopowder particles in the liquid phase after fi lling the intergranular space ; diffusion processes during cooling of the impregnated metal in the solid state. The technology of using nanopowders as hardening agents to obtain a wear-resistant cast composite layer is a promising direction in the foundry industry .
