The results of experimental investigations on the application of electrical discharges in impulse at micro- and nano- surface strata formation are presented in this work. The possibility of meniscuses extraction is demonstrated. It provides the increasing of cathodes active surface area up to 8 times and the increasing of thermo-electronic emission capacity up to 10 times. The surface oxidation occurs at nano-scale depths under the regime of “cold” electrode spots action. The oxide pellicles increases by 10 times the resistance to corrosion of pieces made of construction steel.
