Written by expert authors from both academia and industry with considerable experience in laser material processing, manufacturing and remanufacturing, this book covers the fundamentals, basic science and technologies involved in laser remanufacturing with applications for the repair of worn mechanical components. It introduces the advantages of laser–based remanufacturing technologies and activities as well as the relevant phenomena observed. Several laser remanufacturing techniques and their relevant processing parameters, systems, quality controls and characteristics of the remanufactured parts are discussed, as are efficiency assessment, remanufactured product cycling, technical design and management.
Based on the authors′ research and practice over the last three decades but also incorporating results and examples from other researchers and organizations worldwide, this useful guide includes real–life case studies and numerous examples of applications in various industrial fields, such as transportation vehicles, steel and iron production, energy industries, engineering mechanism, and chemical industries.
