This paper presents an innovative casting method that allows manufacturing the layers on the cast by applying the metallic coating inside the mold. In order to define the possibilities of formation of the metal layers on the castings attempts were made to modify the mold and the cast for models created of two selected plastic materials. The main issue was the choice of a suitable coating material and a casting alloy. The procedure was projected in a manner that would enable the model polymer coating to get into reaction with the cast liquid metal after the burn away. The adjustment of the casting cavity was obtained by the nickel coating. The pit was then filled with the aluminum alloy, when studying the aspects of diffusion and adhesion between the two metals (Ni and Al). On the assumption that nickel coating will generate a diffusion connection with the cast material, it is potential to create intermetallic phases of the system of Ni- Al that will modify the surface attributes of the molding surface. Such designed is to obtain, in a single operation, a ready casting part with a diffusion layer surface.
