Sheds new light on the significance of electrode inhomogeneity and electrochemical heterogeneity A major contribution to the field of electrochemistry, this book—based on a thorough review of the literature and author Yongjun Tan's twenty years of pioneering research—examines electrochemical heterogeneity and its effects on non-uniform electrode processes. The book focuses on localized corrosion, uneven electrodeposition, and non-uniform electrodissolution. Readers will learn all the core fundamentals, experimental methods, and engineering aspects of localized corrosion and other important heterogeneous electrode processes. In particular, readers will learn core methods to quickly calculate corrosion rates and study electrode inhomogeneity and electrochemical heterogeneity. Heterogeneous Electrode Processes and Localized Corrosion begins with a review of homogeneous electrode models and uniform corrosion measurements and then explores probing electrode inhomogeneity, electrochemical heterogeneity, and localized corrosion. Next, the book examines: Visualizing localized corrosion using electrochemically integrated multi-electrode arrays Measuring thermodynamic and kinetic parameters of localized corrosion processes Characterizing inhomogeneity and localized corrosion on coated electrode surfaces Designing experiments to study localized corrosion and its inhibition in inhomogeneous media Sensing localized electrodeposition and electrodissolution Exploring versatile heterogeneous electrode processes Throughout the book, there are case studies with maps that illustrate key aspects of heterogeneous electrode processes. In addition, the author provides plenty of examples that enable readers to fully grasp core concepts of electrochemical heterogeneity and its relationship to non-uniform electrode processes. Reviewing the experimental findings presented in this book, electrochemists will gain a better appreciation and understanding of the fundamental significance of electrode inhomogeneity and electrochemical heterogeneity.

LOCALIZED CORROSION IN COMPLEX ENVIRONMENTS A comprehensive exploration of the monitoring, prediction, and prevention of major forms of localized corrosion in complex industrial environments In Localized Corrosion in Complex Environments, distinguished researcher Dr. Mike Yongjun Tan delivers a solution focused approach to localized corrosion issues in complex environments with the potential to affect structural integrity, public safety, environmental protection, or energy and water deliverability. The book focuses on significant civil and industrial infrastructures exposed to complex corrosion environments, like underground and offshore gas, oil, and water pipelines. The author offers information to help ensure the continued safe operation of aging infrastructures and discusses the limitations of current technologies and the need to continuously develop new and more efficient technologies to manage integrity, prevent structural failures, protect the environment, and reduce operational costs. Readers will also find: A thorough introduction to the major issues relevant to infrastructural corrosion issues Comprehensive explorations of issues likely to affect future fuel and energy infrastructures, like hydrogen containing pipelines and offshore and onshore wind farms Practical discussions of recent progress in inspection and monitoring technologies, as well as the protection provided by protective coatings Fulsome treatments of the use of corrosion inhibitors Perfect for materials and corrosion scientists, physical chemists, engineers, regulators, technologists, and environmentalists, Localized Corrosion in Complex Environments will also earn a place in the libraries of corrosion and materials engineers, maintenance engineers, pipeline engineers, field personnel, and anyone responsible for the integrity of production and transmission of oil, gas, and water.

The effective investigation of corrosion requires the use of methods that can probe material surfaces at the atomic or molecular level and can be used in situ. This important collection reviews the range of techniques available and how they can be used to analyse different types of corrosion.A number of chapters discuss the use of scanning probe microscopy techniques such as electrochemical scanning tunnelling microscopy and atomic force microscopy (EC-STM and EC-AFM). Other chapters analyse local electrochemical techniques such as scanning electrochemical microscopy (SECM), scanning vibrating electrode techniques (SVET), scanning droplet and scanning kelvin probe microscopy (SKFM), as well as microraman spectroscopy and photoelectrochemical imaging. The book reviews the application of these techniques in practice to various metals and types of coating as well as different kinds of corrosion.With its distinguished editors and team of contributors, this is a valuable reference for all those concerned with corrosion research.

Corrosion inhibitors are an important method for minimizing corrosion; however traditional inhibitors such as chromates pose environmental problems. Rare earth metals provide an important, environmentally-friendly alternative. This book provides a comprehensive review of current research and examines how rare earth metals can be used to prevent corrosion and applied to protect metals in such industries as aerospace and construction. Chapter 1 begins by examining the important need to replace chromate, and then goes on to discuss the chemistry of the rare earth metals and their related compounds. Chapter 2 considers the techniques that can be used to identify corrosion inhibition mechanisms and to test the levels of protection offered to different metals by rare earth compounds. Subsequent chapters consider in more detail how rare earth elements can be used as corrosion inhibitors in different forms and for different metals. This includes discussion on the potential of rare earth elements for self-healing, tunable and multifunctional coatings. Finally, chapter 10 considers the cost and availability of the rare earths and the potential health and environmental risks associated with extracting them.
