"This volume is essential for chemical engineers and chemists that design, construct and operate electrochemical plants. Also, maintenance personnel, including materials and mechanical engineers, will benefit from reading, using and owning this compendium, in their daily endeavors. University lecturers and researchers will use it for undergraduate and postgraduate students preparing their theses on industrial corrosion. Electrochemical industry directors and executives should distribute it to the managers and engineers of their plants, to apply it in monitoring and controlling electrocorrosion. We hope that the book will encourage the corrosion community to employ the concepts and the methods that the author has so convincingly presented, to combat electrocorrosion."--Corrosion Engineering, Science and Technology 2010 VOL 45 NO 4 249 "Throughout the book, each chapter is packed with learned references but mainly from the past experience of the author in the Soviet Union without modern up-to-date references from the electrochemical industry in other advanced countries.

Electrocorrosion, the corrosion of metallic constructions by external currents, is the most significant factor in conductive aggressive environments. Corrosion of underground and underwater metal constructions by stray currents has been comprehensively studied in the past decades and is considered here only in the form of a review. The primary attention is on corrosion, by external anodic (mainly) and cathodic currents, of metal constructions in the highly aggressive environments typical for electrochemical plants, where penetration of the external currents (leakage currents) from the electrolytic baths into metal constructions is unavoidable.A new approach to the problem of electrocorrosion protection of passive structural metals is considered in this book, keeping the metals attacked by external currents in the boundaries of their passive field. The systems, developed in accordance with this approach, are based on the modification of existing and elaboration of new methods of electrocorrosion protection. These systems take into account corrosion and electrochemical characteristics of the aggressive media (redox potential, conductivity etc.) and of the passive metal (corrosion and activation potentials, current density in a passive state, etc) as well as the sizes and distribution character of the external currents.The book covers analysis of leakage current distributions in electrochemical plants, their influence, methods to estimate corrosion stability of metallic structures subject to external currents and presents many concrete examples of the successful introduction of corrosion protection systems in operating plants.
