Available in PDF, EPUB and Kindle. Book excerpt: Laser Surface Engineering of Aluminum Alloys presents a comprehensive overview of LSE approaches (laser surface melting, laser alloying, laser cladding, laser composite surfacing, laser shock peening) for all of the Al alloy systems, including the developing 8xxx series alloys. The book discusses in detail the influence of laser processing parameters on the development of microstructure, mechanical/electrochemical properties, residual stresses and defects. Laser surface engineering (LSE) of Al alloys is of considerable scientific and technological interest due to unique processing features such as rapid cooling rate, non-contact heating and superior process control. Aluminum (Al) alloys are the one of the most popular structural materials due to their ductility and high strength-to-weight ratio, and have been extensively used in aircraft, automobile and sports industries. However, these alloys often exhibit insufficient corrosion resistance, stress-corrosion cracking resistance, and wear resistance properties for applications in these industries. Significant efforts are now directed toward modifying the surface characteristics of these alloys for improved surface properties. Provides a comprehensive overview of laser surface processing approaches, including thermal aspects, compositional effects and microstructure development associated with each approach Features separate chapters/sections for all Al alloy systems, including newer emerging systems Provides a valuable reference for further research in the area Covers the techniques used for surface preparation of aluminum alloys for laser processing, including details such as focus parameters, nozzle designs, inert gas and safety relevant to operation of practical laser surface processing set-ups

Available in PDF, EPUB and Kindle. Book excerpt: The major issue of energy saving and conservation of the environment in the world is being emphasized to us to concentrate on lightweight materials in which aluminium alloys are contributing more in applications in the twenty-first century. Aluminium and its related materials possess lighter weight, considerable strength, more corrosion resistance and ductility. Especially from the past one decade, the use of aluminium alloys is increasing in construction field, transportation industries, packaging purposes, automotive, defence, aircraft and electrical sectors. Around 85% is being used in the form of wrought products, which replace the use of cast iron. Further, the major features of aluminium alloy are recyclability and its abundant availability in the world. In general, aluminium and its related materials are being processed via casting, drawing, forging, rolling, extrusion, welding, powder metallurgy process, etc. To improve the physical and mechanical properties, scientists are doing more research and adding some second-phase particles in to it called composites in addition to heat treatment. Therefore, to explore more in this field, the present book has been aimed and focused to bridge all scientists who are working in this field. The main objective of the present book is to focus on aluminium, its alloys and its composites, which include, but are not limited to, the various processing routes and characterization techniques in both macro- and nano-levels.

Download or read book Laser Surface Melting of Carbon Coated AA7075 Aluminum Alloy written by Sourabh Biswas and published by . This book was released on 2014 with total page 63 pages. Available in PDF, EPUB and Kindle. Book excerpt: Carbon is one of the most common solid lubricants and has often been used to achieve superior tribological properties. In this investigation, a CO2 laser in continuous wave mode was used to develop diamond-like carbon (DLC)-rich coatings on 7075 alloys. A detailed investigation on the effect of the in-situ transformed DLC and graphitic nanoparticles on the tribological properties of the 7075 alloys was performed. A unique relationship between the surface hardness and wear rate was noted, wherein the wear rate decreased with decrease in surface hardness after the laser surface engineering. An analysis of wear track and counterbody using EDS and Raman spectroscopy confirmed the formation of metastable DLC-rich graphitic tribolayer during the wear process. A `reverse' transformation of the apparently more stable graphitic carbon to metastable DLCs in the tribolayer during frictional loadings was also noticed. The tribolayer was noted to generate significant lubricating action, and therefore, improve the wear resistance. Also, unlike the loss in lubricating action with increasing time usually exhibited by non-hydrogenated DLCs, the increase in nano-carbon rich melt-zone was observed to partially mitigate this effect by enabling presence of lubricating particles even at greater depths from the surface.

Available in PDF, EPUB and Kindle. Book excerpt: This book is an outcome of the NATO institute on surface modification which was held in Trevi, 1981. Surface modification and alloying by ion, electron or laser beams is proving to be one of the most burgeoning areas of materials science. The field covers such diverse areas as integrated circuit processing to fabricating wear and corrosion resistant surfaces on mechanical components. The common scientific questions of interest are the microstructures by the different energy deposition techniques. and associated physical properties produced The chapters constitute a critical review of the various subjects covered at Trevi. Each chapter author took responsibility for the overall review and used contributions from the many papers presented at the meeting; each participant gave a presentation. The contributors are listed at the start of each chapter. We took this approach to get some order in a large and diverse field. We are indebted to all the contributors, in particular the chapter authors for working the many papers into coherent packages; to Jim Mayer for hosting a workshop of chapter authors at Cornell and to Ian Bubb who did a sterling job in working over some of the manuscripts. Our special thanks are due to the text processing center at Bell Labs who took on the task of assembling the book. In particular Karen Lieb and Beverly Heravi typed the whole manuscript and had the entire book phototypeset using the Bell Laboratories UNIXTM system.

This book was released on 2018 with total page 39 pages. Available in PDF, EPUB and Kindle. Book excerpt: This article presents a comprehensive literature study showing contemporary industrial applications of laser processing of materials in the area of surface engineering. Laser remelting, alloying, feathering, and cladding are discussed. The results of our own research on the application of laser technologies for surface treatment, including hot work tool alloy steels, high-speed steels, magnesium and aluminum alloys, are presented. The production of porous titanium microskeletons prepared using the additive selective laser sintering (SLS) method for the production of original biological engineering materials and implants-scaffolds is presented. The laser texturing of polycrystalline silicon is also presented after texturing requiring etching in alkaline solutions and preferably also after applying antireflective coatings. The article also presents the use of SLS for the application of electrical contacts on photovoltaic cells. Identification of the critical surface of engineering technologies has been presented. Attention was paid to select 21 technologies, which were included in the group of laser processing of materials, from 500 critical technologies of surface engineering that were analyzed with our own methodology of technological foresight. In order to determine the strategic position of individual groups of critical technologies, an original set of context matrices was developed, including the dendrological matrix of technology values and the meteorological matrix of environmental impact, and the results were summarized in a sixteen-field strategy matrix for technologies. A 20-year time horizon of heuristic research was established. It has been shown that the analyzed technologies of laser processing of materials are finding wider and wider application in modern technology so that their significant development in the next two decades should be expected. It has been pointed out that laser surface technologies, because of their high development potential demonstrated by the performed foresight research, are some of the important elements of the development of the Industry 4.0 idea.
