The structure and phase composition of coatings formed on the surface of the EP648 alloy were studied using the hot-dip aluminizing method with subsequent heat treatment. Aluminizing allows one to form a continuous aluminide coating with a clearly distinguishable layered structure, in which the upper layer is represented by (Al) with eutectic inclusions, the middle layer consists of (Al) and intermetallics mixture, and the thin boundary layer has a φ + κ / φ / Ni2Al3(Cr) structure. Treatment of the aluminized EP648 alloy at 1100 °C allows one to get rid of the (Al) phase and form an intermetallic coating due to the diffusion redistribution of chemical elements.
