In this paper, the anticorrosive properties of inhibitors (inh) - products of fruit and berry raw materials (fruit juice) are investigated on the example of a galvanic cell with irreversible electrodes. The test sample of aluminum Rus-grade “AД1пл” according to «ГОСТ 4784-1997» serves as the cathode, and the roughly processed sample of copper Rus-grade “M00к” according to “ГОСТ 859-2014” serves as an anode (to minimize the polarization of hydrogen evolution). Samples were pre-degreased. A measure of the change in the corrosion process is a function of the time of the magnitude of the current of the galvanic cell, which, in turn, depends on the degree of anodic hydrogen depolarization.
