This book is concerned with providing a fundamental basis for understanding the alloy-gas oxidation and corrosion reactions observed in practice and in the laboratory. Starting with a review of the enabling thermodynamic and kinetic theory, it analyzes reacting systems of increasing complexity. It considers in turn corrosion of a pure metal by a single oxidant and by multi-oxidant gases, followed by corrosion of alloys producing a single oxide then multiple reaction products. The concept of "diffusion paths is used in describing the distribution of products in reacting systems, and diffusion data is used to predict reaction rates whenever possible. - Provides a logical and expert treatment of the subject for use as a guide for advanced-level academics, researchers and practitioners - Text is well supported by numerous micrographs, phase diagrams and tabulations of relevant thermodynamic and kinetic data - Combines physical chemistry and materials science methodologies
