Abstract

By the methods of corrosion chronopotentiometry, voltammetry, and electrochemical impedance spectroscopy, we investigate the dependence of the electrochemical parameters of the corrosion of amorphous alloys of aluminum Al87.0Y5.0Ni80 , Al87.0Gd5.0Ni8.0, Al87.0Y4.0Gd1.0Ni8.0 , Al87.0Gd5.0Ni4.0Fe4.0 , and Al87.0Y4.0Gd1.0Ni4.0Fe4.0 on the temperature of treatment and deposition of oligoperoxide protective coatings on the surface. It is shown that the efficiency of the formed layer is determined by the compositions of oligoperoxide solutions and the content of rare-earth alloying additions in these alloys.
