Dependences of developed electrode materials (alloys of systems Ni-Cr-Al, Fe-Cr-Al, Fe-Cr-Ni and AlN-MoSi2) erosive properties from phase structure and manufacturing conditions are studied. Regularities of protective coatings formation, structure and properties are established, giving the basis to development of new effective electrode materials. The structure and manufacturing technology of electrode materials are op- timized considering mass transfer intensity during electrospark hardening and properties level (wear resis- tance and heat resistance). The developed materials are used for increase of various constructions details operation term.
