Studies have shown that corrosion resistance of structural steels contacting Pb and Pb-Bi coolants can be increased by introducing Al into the steel surface layer: first, Al coating is applied to the surface, then the surface is treated by an intense pulsed electron beam. Experimental facility for realization of this procedure is described in the report. The facility consists of magnetron for Al coating preparation and electron accelerator producing radial converging electron beam.
