CORROSION-ELECTROCHEMICAL BEHAVIOUR OF ALUMINIUM ALLOYS IN NEUTRAL MEDIA RELATIVELY TO DEVELOPMENT OF PROTECTORS

The work covers the aluminium alloys with iron, silicon and zinc. The aim of the work is to study the aluminium alloy composition on its corrosion and electrochemical behaviour in the anode polarization conditions. The dependences of the difference-effect on the alloy composition have been determined, the cause of strong decreasing use efficiency coefficient of the Al-Zn-Fe has been determined that has been connected with secondary participation process in the ferrum ion depolarization reactions. A possibility to use the secondary aluminium for making effective halvanic anodes has been shown. The protector alloy composition has been developed.
