The dependence of the mass transfer parameters on the structure of the Ni–Cr–Al and Ni–Cr–NiAl electrode systems in the electrospark alloying of steel 45 is studied. The phase composition of the cast, sin tered, and hot pressed alloys is a mixture of solid solutions based on nickel, chromium, and NiAl intermet allide. The mass transfer coefficient in the case of alloying with cast and hot pressed alloys is 2 to 3.5 times
higher than that in the event of alloying with sintered alloys. This difference is due to the different structures of the electrodes prepared by different techniques.
