Download or read book Comprehensive Materials Finishing written by M.S.J. Hashmi and published by Elsevier. This book was released on 2016-08-29 with total page 1467 pages. Available in PDF, EPUB and Kindle. Book excerpt: Finish Manufacturing Processes are those final stage processing techniques which are deployed to bring a product to readiness for marketing and putting in service. Over recent decades a number of finish manufacturing processes have been newly developed by researchers and technologists. Many of these developments have been reported and illustrated in existing literature in a piecemeal manner or in relation only to specific applications. For the first time, Comprehensive Materials Finishing, Three Volume Set integrates a wide body of this knowledge and understanding into a single, comprehensive work. Containing a mixture of review articles, case studies and research findings resulting from R & D activities in industrial and academic domains, this reference work focuses on how some finish manufacturing processes are advantageous for a broad range of technologies. These include applicability, energy and technological costs as well as practicability of implementation. The work covers a wide range of materials such as ferrous, non-ferrous and polymeric materials. There are three main distinct types of finishing processes: Surface Treatment by which the properties of the material are modified without generally changing the physical dimensions of the surface; Finish Machining Processes by which a small layer of material is removed from the surface by various machining processes to render improved surface characteristics; and Surface Coating Processes by which the surface properties are improved by adding fine layer(s) of materials with superior surface characteristics. Each of these primary finishing processes is presented in its own volume for ease of use, making Comprehensive Materials Finishing an essential reference source for researchers and professionals at all career stages in academia and industry. Provides an interdisciplinary focus, allowing readers to become familiar with the broad range of uses for materials finishing Brings together all known research in materials finishing in a single reference for the first time Includes case studies that illustrate theory and show how it is applied in practice

Download or read book Natural Stone and Architectural Heritage written by Giovanna Antonella Dino and published by MDPI. This book was released on 2019-09-23 with total page 262 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is made up of contributions dealing with heritage stones from different countries around the world. The stones are described, as well as their use in vernacular and contemporaneous architecture. Heritage stones are those stones that have special significance in human culture. Examples include some very important stones that have been either neglected because they are no longer extracted, or stones that have great significance in commercial terms but knowledge of their national and/or international heritage has not been well documented. In this collection of articles, we have tried to spread awareness of architectural heritage around the world, the natural stones that have been used in its construction, and the need to preserve historical quarries that once provided the source of such stones. Historical quarries are linked to regional culture and tradition. Because of the specific technical and aesthetical characteristics of heritage stones, which have lasted for centuries, these historical quarries should be preserved to be able to use the stones for the proper restoration of monuments and historical buildings to avoid negative actions that can be observed in many places in the restoration of buildings, which are some times part of World Heritage sites. The final intention of this book is to continuosly grow the interest on this fascinating subject of heritage stones.

Download or read book Handbook of Liquids Assisted Laser Processing written by Arvi Kruusing and published by Elsevier. This book was released on 2010-07-07 with total page 465 pages. Available in PDF, EPUB and Kindle. Book excerpt: Laser processing of solid materials has been commonly performed in gas ambient. Having the workpiece immersed into liquid, having a liquid film on it, or soaking the material with liquid gives several advantages such as removal of the debris, lowering the heat load on the workpiece, and confining the vapour and plasma, resulting in higher shock pressure on the surface. Introduced in the 1980s, neutral liquids assisted laser processing (LALP) has proved to be advantageous in the cutting of heat-sensitive materials, shock peening of machine parts, cleaning of surfaces, fabrication of micro-optical components, and for generation of nanoparticles in liquids. The liquids used range from water through organic solvents to cryoliquids. The primary aim of Handbook of Liquids-Assisted Laser Processing is to present the essentials of previous research (tabulated data of experimental conditions and results), and help researchers develop new processing and diagnostics techniques (presenting data of liquids and a review of physical phenomena associated with LALP). Engineers can use the research results and technological innovation information to plan their materials processing tasks. Laser processing in liquids has been applied to a number of different tasks in various fields such as mechanical engineering, microengineering, chemistry, optics, and bioscience. A comprehensive glossary with definitions of the terms and explanations has been added. The book covers the use of chemically inert liquids under normal conditions.

Download or read book Microscale Surface Tension and Its Applications written by Pierre Lambert and published by MDPI. This book was released on 2019-10-21 with total page 240 pages. Available in PDF, EPUB and Kindle. Book excerpt: Building on advances in miniaturization and soft matter, surface tension effects are a major key to the development of soft/fluidic microrobotics. Benefiting from scaling laws, surface tension and capillary effects can enable sensing, actuation, adhesion, confinement, compliance, and other structural and functional properties necessary in micro- and nanosystems. Various applications are under development: microfluidic and lab-on-chip devices, soft gripping and manipulation of particles, colloidal and interfacial assemblies, fluidic/droplet mechatronics. The capillary action is ubiquitous in drops, bubbles and menisci, opening a broad spectrum of technological solutions and scientific investigations. Identified grand challenges to the establishment of fluidic microrobotics include mastering the dynamics of capillary effects, controlling the hysteresis arising from wetting and evaporation, improving the dispensing and handling of tiny droplets, and developing a mechatronic approach for the control and programming of surface tension effects. In this Special Issue of Micromachines, we invite contributions covering all aspects of microscale engineering relying on surface tension. Particularly, we welcome contributions on fundamentals or applications related to: Drop-botics: fluidic or surface tension-based micro/nanorobotics: capillary manipulation, gripping, and actuation, sensing, folding, propulsion and bio-inspired solutions; Control of surface tension effects: surface tension gradients, active surfactants, thermocapillarity, electrowetting, elastocapillarity; Handling of droplets, bubbles and liquid bridges: dispensing, confinement, displacement, stretching, rupture, evaporation; Capillary forces: modelling, measurement, simulation; Interfacial engineering: smart liquids, surface treatments; Interfacial fluidic and capillary assembly of colloids and devices; Biological applications of surface tension, including lab-on-chip and organ-on-chip systems.

Download or read book Investigation of the Self organising Behaviour of Laser Implanted Tool Surfaces written by Hilgenberg, Kai and published by kassel university press GmbH. This book was released on 2014-01-01 with total page 154 pages. Available in PDF, EPUB and Kindle. Book excerpt: The alignment of defined surface structures on sheet metal surfaces for metal forming operations by skin-pass rolling is a common approach for improving the formability, the durability of the used forming tools, and the optical appearance of the final product. Especially automotive applications impose high requirements on the properties and the repeatability of surface structures. Different roll structuring techniques have therefore been developed during the last decades and found entrance into industrial application. However, the lifetime of the structured rolls is still not satisfying, which necessitates expensive and time consuming chrome plating and roll replacement. Furthermore, a study of the state of the art reveals that the tribological potential of defined surface structures for enabling micro-lubrication mechanisms in subsequent forming steps is apparently not realised completely by these techniques.

In experimental studies a new structuring method is investigated for optimising the tribological behaviour in metal forming operations. This new approach utilises the system immanent wear forces for the creation and maintenance of a surface topology. It bases on the initial creation of a material properties gradient on the surface of tool steels, which is gradually transformed into a surface topology under tribological load due to locally different wear rates. For the creation of the necessary material properties gradient, a discontinuous laser dispersing (laser implantation) of ceramic particles is further developed.

The wear behaviour and its influence parameters are identified in sliding and rolling wear experiments. It is shown in a pin-on-disc test that after a certain time a steady state exists where the created surface topology does not change. This state is not reached in the rolling test due to the outstanding wear performance of the laser created structures, the comparably low relative sliding velocity and the distribution of the wear effect on the roll circumference. Afterwards, a mathematic model basing on contact-mechanical considerations is introduced, which allows a prediction of the wear behaviour and the steady state height. It shows a good agreement with the experimental results. Finally, the potential of the laser implantation texturing for being used in industrial applications is discussed.
