FIELD: protection against corrosion. SUBSTANCE: device has substrate which is made from porous ceramics and has rectangular shape. Each flat surface of substrate has metal electrodes, which are made from different metals copper and titan and are deposited to substrate by plasma evaporation. Both sides of substrate have additional electrode, which is made from same material as construction to be protected and which is deposited to substrate by plasma evaporation. EFFECT: increased functional capabilities. 5 dwg
