"With the increasing demand to enhance product competitiveness, the automobile industry is concentrating on weight reduction, which has proven to improve fuel efficiency, reduce exhaust emission and assure enhanced safety and vehicle driving performance. Hence, Aluminum Matrix Composite (AMC) materials reinforced with ceramic particles are most sought after to achieve these goals ... Although adding a second phase improves strength, hardness, and wear among other properties, it has detrimental effects on properties such as ductility ... This study advances the development of FSP as an effective AMSC fabrication technique"--Introduction, leaf 1.

Volume is indexed by Thomson Reuters BCI (WoS). All components and mechanical parts have surfaces which are either exposed to a particular environment or are in contact with other components. Consequent corrosion and/or wear of the surface may then lead to destructive failure. A so-called “bad” surface is a favoured spot for crack initiation, resulting in a decrease in the fatigue, tensile properties and even toughness of materials. Although the development of new materials can improve the surface properties, this can also lead to a change in the properties of the substrate. For example, increasing the carbon content significantly improves the wear resistance of steels, but toughness has to be sacrificed. Increased cost is another major concern. Moreover, for some components, such as gears, a ductile substrate and a hard surface are required. In this case, surface treatment remains the only choice. Surface modification, also termed surface treatment, has thus been recognised as being a major emergent manufacturing technology for improving the surface properties, with minimal alteration of the substrate.

This book combines the contributions of experts in the field to describe the behavior of various materials, micromechanisms involved during processing, and the optimization of cold-spray technology. It spans production, characterization, and applications including wear resistance, fatigue, life improvement, thermal barriers, crack repair, and biological applications. Cold spray is an innovative coating technology based on the kinetic energy gained by particles sprayed at very high pressures. While the technique was developed in the 1990s, industrial and scientific interest in this technology has grown vastly in the last ten years. Recently, many interesting applications have been associated with cold-sprayed coatings, including wear resistance, fatigue life improvement, thermal barriers, biological applications, and crack repair. However, many fundamental aspects require clarification and description.

This fully revised, industry-standard resource offers practical details on every aspect of the fundamentals necessary for understanding thermal spray technology, from powder all the way to the final part. The second edition is presented in a reader-friendly format that is split into four parts. Part I presents a review of thermal spray coating and its position in the broad field of surface modification technologies. Highlights of combustion and thermal plasmas are given with an expanded treatment of in-flight plasma-particle interactions. The second and third parts deal respectively with an updated presentation of thermal spray technologies and coating formation, including solution and suspension plasma spraying. The last part of the book includes a comparative analysis of different thermal spray processes, which is essential for the optimal selection of the appropriate thermal spray process in a given application. Coverage of system integration has been expanded with the addition of a detailed discussion of online instrumentation and process diagnostics and numerous examples of industrial scale spray booth designs. Attention is also given to coating finishing and health and safety issues. An extensive review is presented of thermal spray applications grouped in terms of process objectives and present use in different industrial sectors. This book will serve as an invaluable resource as a textbook for graduate courses in the field and as an exhaustive reference for professionals involved in the thermal spray field.

Plasma electrolytic oxidation (PEO), also known as micro-arc oxidation (MAO), functionalizes surfaces, improving the mechanical, thermal, and corrosion performance of metallic substrates, along with other tailored properties (e.g., biocompatibility, catalysis, antibacterial response, self-lubrication, etc.). The extensive field of applications of this technique ranges from structural components, in particular, in the transport sector, to more advanced fields, such as bioengineering. The present Special Issue covers the latest advances in PEO‐coated light alloys for structural (Al, Mg) and biomedical applications (Ti, Mg), with 10 research papers and 1 review from leading research groups around the world.
