Hot Corrosion and Oxidation Behaviour of TiAl Alloys during Fabrication by Laser Powder Bed Additive Manufacturing Process *by Ntebogeng Mogale, Wallace Matizamhuka and Prince Cobbinah*

Preface

Although a natural process, corrosion in materials is responsible for huge direct as well as indirect losses around the world. This book explores the impact of corrosion products on the performance of devices, especially those incorporating metals or metal derivatives. It also discusses corrosion prevention mechanisms, the role of inhibitors in various oil/gas pipeline industries to avoid fatal accidents, and the growth of natural inhibitors over inorganic or organic inhibitors to support the concept of the "green" approach. Furthermore, the book presents the basics of corrosion from thermodynamic and kinetic points of view, discusses the major driving force behind

The book is divided into three sections. The first section discusses the fundamentals of corrosion and the driving force behind the process, types, and possible mechanisms involved. The second section provides insight into corrosion inhibitors and the third section discusses the characterization aspects in corrosion sciences with developmental trends associated with computational analysis of corrosion. The impact of computational methodologies like density functional theory and molecular dynamics simulations for the identification of suitable inhibitors is presented. The practical relevance of additives in the manufacturing of alloys using laser powder bed fusion technology is also summarized along with the concept of high-temperature corrosion (hot corrosion). Overall, this book is beneficial for students and researchers who are interested in the field of corrosion sciences, polymer technology, and the
