Book Description
Capitalizing on the rapid growth and reduced costs of laser systems, laser cladding is gaining momentum, and in some instances replacing conventional techniques of depositing thin films because it can accommodate a great variety of materials, achieve uniform thickness and precise widths of layers, and provide improved resistance to wear and corrosion in the final product. Laser cladding technology also offers a revolutionary layered manufacturing and prototyping technique that can fabricate complex components without intermediate steps. Laser Cladding reviews the parameters, techniques and equipment, process modeling and control, and the physical metallurgy of alloying and solidification during laser cladding. The authors clarify the interconnections laser cladding has with CAD/CAM design; automation and robotics; sensors, feedback, and control; physics, material science, heat transfer, fluid dynamics, and powder metallurgy to promote further development and improved process quality of this growing technology. As the first book entirely dedicated to the topic, it also offers a history of its development and a guide to applications and market opportunities. While a considerable part of Laser Cladding is dedicated to industrial applications, this volume brings together valuable information illustrated with real case studies based on the authors' vast experience, and research and analysis in the field to provide a timely source for both academia and industry.

Book Description
Laser cladding is an additive manufacturing technology capable of producing coatings due to the surface fusion of metals. The selected powder is fed into a focused laser beam to be melted and deposited as coating. This allows to apply material in a selected way onto those required sections of complex components. The process main properties are the production of a perfect metallurgically bonded and fully dense coatings; the minimal heat affected zone and low dilution between the substrate and filler material resulting in functional coatings that perform at reduced thickness, so fewer layers are applied; fine, homogeneous microstructure resulting from the rapid solidification rate that promotes wear resistance of carbide coatings; near net-shape weld build-up requires little finishing effort; extended weldability of sensitive materials like carbon-rich steels or nickel-based superalloys that are difficult or even impossible to weld using conventional welding processes; post-weld heat treatment is often eliminated as the small heat affected zone minimizes component stress; excellent process stability and reproducibility because it is numerical controlled welding process. The typical applications are the dimensional restoration; the wear and corrosion protection; additive manufacturing. The wide range of materials that can be deposited and its suitability for treating small areas make laser cladding particularly appropriate to tailor surface properties to local service requirements and it opens up a new perspective for surface engineered materials. The main key aspect to be scientifically and technologically explored are the type of laser; the powders properties; the processing parameters; the consequent microstructural and mechanical properties of the processed material; the capability of fabrication of prototypes to rapid tooling and rapid manufacturing. Distills critical concepts, methods, and applications from leading full-length chapters, along with the authors’s own deep understanding of the material taught, into a concise yet rigorous graduate and advanced undergraduate text; Reinforces concepts covered with detailed solutions to illuminating and challenging industrial applications; Discusses current and future applications of laser cladding in additive manufacturing.

Book Description
It is one oft he major challenges for materials scientists and mechanical engineers to cope with the demands for long lasting and reliable systems in all markets and for all applications. The loss of energy by friction and the limits of endurance by wear can be countered by well selected materials and surfaces. The economical and ecological significance of wear and friction is undisputed and can equate to between 1 and 4% of the gross national products of industrial countries. Although the basic understanding of the mechanisms of friction and wear has drastically increased during the last five decades, many technical solutions are still carried out "following trial and error". Selection of the best material and the optimal topography in combination with the desired physical and chemical properties requires a systematic approach and a deep understanding of the acting mechanisms. Thus friction, wear, and wear protection are interdisciplinary fields which bring together scientists from the engineering, natural, biological and medical sciences. This book is an indispensable source for everybody who needs to solve the problems of friction and wear on materials.
