This book was written to provide a good understanding of diffusion in solids. The topic of diffusion is important because it covers several metallurgical and heat-treatment processes. This book gives an overview of the solid-state diffusion processes and covers the fundamental laws governing the diffusion process and the factors affecting diffusion processes. Different heat-treatment processes involving diffusion coatings are thoroughly discussed, along with relevant application benefits. The book also includes the data required to perform diffusion-related calculations. It correlates theory with the use of diffusion laws in practice to predict the end result.

This book also aims to train engineers and professionals on how to solve problems related to diffusion in solids. The problems included in the Appendix: Diffusion in Solids—Problems and Solutions in this book include a variety of diffusion processes and cases involving different materials and substrates.
