Abstract
The relations between the erosion properties of the developed electrode materials (the alloys of the systems Ni-Cr-Al, Fe-Cr-Al, Fe-Cr-Ni, and AlN-MoSi2) and the phase structure and manufacturing conditions are studied. The regularities of the formation of the protective coatings and their structure and properties are established, which makes it possible to develop new highly efficient electrode materials. The composition of the electrode materials and the manufacturing processes have been optimized considering the rate of the mass transfer in the course of the electrospark hardening and the main properties (wear resistance and heat resistance). The developed materials are used to increase the service life of various parts.
