THE USE OF FRUIT FRESH JUICES AS INHIBITORS OF ALUMINIUM ELECTROCHEMICAL CORROSION IN ALKALINE MEDIUM

Abstract

In this article, the anticorrosion properties of inhibitors (that is, fruit and berry processing products) are studied using an electrochemical cell with irreversible electrodes as an example, in which cathode surface (aluminum sample for testing the class “AD1 pl”) is highly renewable. A sample of crudely processed copper (needed to minimize polarization at hydrogen evolution) of the “M00 k” class serves as an anode. A measure for corrosion is a change in the amperage of a galvanic electrochemical cell.
