Book Description
Combined erosion-corrosion poses a considerable problem to the design of long lifetime metallic components in energy conversion systems. To gain some insight into this problem, scales were formed on stainless steel at elevated temperature and subsequently were eroded at room temperature to determine the nature of the erosion rates and the mechanism of scale removal. Thin corrosion scales were formed on 310 stainless steel and an experimental Fe-18Cr-5Al-1Hf alloy at high temperatures (9ooo and 980°C) in gas mixtures with various levels of oxygen and combined oxygen-sulfur. The corroded specimens were eroded at room temperature in an air-solid particle stream using 50{micro}m SiC at 60 ms−1. The conditions of the corrosive exposures, the rates of erosion of these scales and the microscopic appearance of the eroded surface were correlated to determine the mechanism of thin scale erosion.

Book Description
The presence of small particles of coal and char in moving reactive gases at elevated temperatures in coal gasifiers creates a hostile environment that has caused surface degradation of metallic components in pilot plant operations. The objective of the work reported herein is to provide some insight into the basic mechanisms of degradation that occur when a small particle impacts on a bare metal surface or on one that contains a thin oxide scale. It is hoped that understanding how material is removed from the surface will provide the basis for selecting operating conditions and developing more resistant materials that will result in less materials degradation. The work to date indicates that significant differences in erosion behavior do occur as the result of different elevated temperature corrosion conditions forming different scale and interface compositions and morphologies. Generally the differences were relatively minor. However, under conditions of combined erosion-corrosion, these differences could become important. Even though the scales were thin and on ductile matrices, their erosion behavior variation with impingment angle was that of a brittle rather than a ductile material. The use of erosion tests to study the adherence of various scales has some merit. However interpretation of some of the smaller differences could be difficult.

Book Description
High temperature corrosion is a phenomenon that occurs in components that operate at very high temperatures, such as gas turbines, jet engines and industrial plants. Engineers are constantly striving to understand and prevent this type of corrosion. This book examines the latest developments in the understanding of high temperature corrosion processes and protective oxide scales and coatings. Part one looks at high temperature corrosion. Chapters cover diffusion and solid state reactions, external and internal oxidation of alloys, metal dusting corrosion, tribological degradation, hot corrosion, and oxide scales on hot-rolled steel strips. Modern techniques for analysing high temperature oxidation and corrosion are also discussed. Part two discusses methods of protection using ceramics, composites, protective oxide scales and coatings. Chapters focus on layered ternary ceramics, alumina scales, Ti-Al intermetallic compounds, metal matrix composites, chemical vapour deposited silicon carbide, nanocrystalline coatings and thermal barrier coatings. Part three provides case studies illustrating some of the challenges of high temperature corrosion to industry and how they can be overcome. Case studies include the petrochemical industry, modern incinerators and oxidation processing of electronic materials. This book is a valuable reference tool for engineers who develop heat resistant materials, mechanical engineers who design and maintain high temperature equipment and plant, and research scientists and students who study high temperature corrosion and protection of materials. Describes the latest developments in understanding high temperature corrosion Presents the latest research by the leading innovators from around the globe Case studies are provided to illustrate key points

Book Description
George Lai's 1990 book, High-Temperature Corrosion of Engineering Alloys, is recognized as authoritative and is frequently consulted and often cited by those in the industry. His new book, almost double in size with seven more chapters, addresses the new concerns, new technologies, and new materials available for those engaged in high-temperature applications. As we strive for energy efficiency, the realm of high-temperature environments is expanding and the need for information on high temperature materials applications was never greater. In addition to extensive expansion on most of the content of the original book, new topics include erosion and erosion-corrosion, low NOx combustion in coal-fired boilers, fluidized bed combustion, and the special demands of waste-to-energy boilers, waste incinerators, and black liquor recovery boilers in the pulp and paper industry. The corrosion induced by liquid metals is discussed and protection options are presented.

Book Description
High temperature corrosion is an extremely important area of corrosion as it causes the failure of high temperature equipment in process industry and power generation. Every engineer is required to obtain a basic knowledge of high temperature corrosion to prevent the colossal damage caused by it. This book contains chapters ranging from basic to advance topics to create an understanding of high temperature of various metals and alloys. With the emerging technologies such as nanotechnology, their role in controlling high temperature corrosion needs to be comprehended and new techniques developed to control high temperature corrosion. It is hoped that this book would fulfill these objectives and aspirations of the readers. Note from the publisher: It is with great sadness and regret that we inform the contributing authors and future readers of this book that the Editor, Prof. Zaki Ahmad passed away shortly after finishing the book and before having a chance to see its publication. Prof. Ahmad was InTech's long term collaborator and edited his first book with us in 2011 (''Recent Trends in Processing and Degradation of Aluminium Alloys''). The book ''High Temperature Corrosion'' was his fourth edited volume. The fruitful collaboration continued until his final days when he was acting as a co-editor on a book ''Wastewater Treatment and Resource Recovery''. We would like to acknowledge Dr. Zaki Ahmad's contribution to open access scientific publishing, which he made during 6 years of dedicated work on edited volumes and express our gratitude for his pleasant cooperation with us.
