Abstract—A possibility for the incorporation of alloying elements to the surface of a steel powder intended for 3D printing is demonstrated using a chemical heat treatment via a transport method involving iodine as a transport agent. The results of aluminum, tungsten, manganese, nickel, titanium and chromium transport are presented.
