Abstract

Experimental study was performed on the influence of nanosized refractory nanopowders on the structure and electrochemical characteristics of aluminum alloy AlZn4 used as protective anode. It was found that modification of alloy AlZn4 with nanopowder of aluminum nitride or diamond induces refining of alloy structure by the factor of 1.5, increases the anode strength and its protective negative potential. Those factors have practical value for higher efficiency of protection from corrosion in water-contacting vessels.
