Abstract: 

The reasonableness of preliminary electrospark alloying of the aluminum base and simultaneous electrospark treatment of the epoxy composition with the subsequent formation of the coating is substantiated. The relevance of the application of dispersed particles with ferromagnetic nature as fillers is experimentally substantiated. Such additives, irrespectively of their chemical, thermodynamic and kinetic activity, significantly affect the degree of binder cross-linking in the surface layers around the fillers and significantly increase physical-mechanical properties of the materials and protective coatings formed on their basis.

Keywords: 
epoxy composite, interaction mechanism, electrospark treatment, degree of cross-linking, substrate, adhesive strength, phase separation interface.
