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 "e;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
