Abstract

Requirements upon the electrodes (anodes and cathodes) for the developed methods of protection against corrosion by leakage currents coincide but partially with the requirements that are imposed upon the electrodes which are used in electrolysis processes and in other areas. Application of commercial anodes for protection from electrocorrosion in neutral and acid chlorides and in sulfate containing media is considered. Results of the investigation of new anodes in chloride and in chloride-alkali solutions are given. The anodes were obtained on the basis of intermetallic compounds produced in an electric spark. Stable cathodes which were developed for chloride media containing dissolved chlorine are considered. Possibility of increasing the stability of titanium cathode blanks by oxidizing titanium surface is discussed.
