Download or read book Scratching of Materials and Applications written by Sujeet K. Kumar Sinha and published by Elsevier. This book was released on 2006-09-29 with total page 334 pages. Available in PDF, EPUB and Kindle. Book excerpt: The surface characterizations of engineering materials effects their scratch/abrasion/Mar resistance, coating adhesion/strength, and abrasive wear mechanism. Scratching of Materials and Applications has chapters devoted to direct industrial application and contains some of the important works that are being conducted. Scratch testing of materials has grown extensively since the earlier days of the Mohs Scale for ranking minerals according to their relative scratch resistance. This test has been used on metals, ceramics, glasses, polymers and coatings of various types and thicknesses.The chapters are grouped according to the type of the engineering materials used. The beginning chapters relate mostly to bulk polymers, which are followed by different types of coatings (hard wear resistant to the diamond-like carbon coatings) and finally, chapters on the application of scratching technique to metals and ceramics are included at the end of the book. Thus, the book covers a fairly wide spectrum of engineering materials which are useful to engineers and researchers.* Balances theoretical science with practical application* Demonstrates real-life applications within industry* Written experts in the fields of materials, tribology and surface mechanics

Available in PDF, EPUB and Kindle. Book excerpt: To this point, the field of lubrication has been conceptualized using several noncontiguous modes of operation — boundary, fluid-film, and dry and solid lubrication. Engineers and analysts have long had to deal with old evidence that many tribological devices, such as flat surface and centrally pivoted sliders, can act as viable bearings — contradicting basic hydrodynamic theory. Tribology of Interface Layers introduces a new concept wherein disparate modes are shown to actually be particular phases of a tribological continuum spanning a wide array of material lubricants. The author details these phenomena and presents a novel definition of lubricants as intermediate layers. Explores the phenomenon of continuum spectrum as applied to new powder lubrication technology The book illustrates that contrary to previous understanding, the various lubrication modes — from dry to hydrodynamic to powder lubrication — all overlap each other within a tribological spectral continuum. It also elucidates the fact that bearings, seals, dampers, and similar devices using submicron powder lubricants possess quasi-hydrodynamic characteristics akin to conventional fluid films. Similarly, powder films possess quasi-hydrodynamic features that enable them to act as conventional fluid film bearings. The field of tribology has traditionally been presented in terms of disparate regimes, but this method of classification lacked sufficient rigor. This volume explains that characterization and treatment of any one regime may require the simultaneous accounting of several different modalities that are present in a particular mode of operation. Based on experimental and theoretical work, this text shows how the interdependence of powder and hydrodynamic lubrication exemplifies that perpetuity in tribological processes. Author Hooshang Heshmat was on hand for a book signing at the 2010 STLE Meeting. Dr. Heshmat was the 2007 recipient of the Mayo D. Hersey Award, bestowed on an individual in recognition of distinguished and continuous contributions over a substantial period of time to the advancement of the science and engineering of tribology.

Download or read book High Pressure Rheology for Quantitative Elastohydrodynamics written by Scott S. Bair and published by Elsevier. This book was released on 2007-03-06 with total page 262 pages. Available in PDF, EPUB and Kindle. Book excerpt: Computational elastohydrodynamics, a part of tribology, has existed happily enough for about fifty years without the use of accurate models for the rheology of the liquids used as lubricants. For low molecular weight liquids, such as low viscosity mineral oils, it has been possible to calculate, with precision, the film thickness in a concentrated contact provided that the pressure and temperature are relatively low, even when the pressure variation of viscosity is not accurately modelled in detail. Other successes have been more qualitative in nature, using effective properties which come from the fitting of parameters used in calculations to experimental measurements of the contact behaviour, friction or film thickness. High Pressure Rheology for Quantitative Elastohydrodynamics is intended to provide a sufficiently accurate framework for the rheology of liquids at elevated pressure that it may be possible for computational elastohydrodynamics to discover the relationships between the behaviour of a lubricated concentrated contact and the measurable properties of the liquid lubricant. The required high-pressure measurement techniques are revealed in detail and data are presented for chemically well-defined liquids that may be used as quantitative reference materials.* Presents the property relations required for a quantitative calculation of the tribological behaviour of lubricated concentrated contacts.* Details of high-pressure experimental techniques.* Complete description of the pressure and temperature dependence of viscosity for high pressures.* Some little-known limitations on EHL modelling.

Download or read book Fundamentals of Tribology and Bridging the Gap Between the Macro and Micro Nanoscales written by Bharat Bhushan and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 961 pages. Available in PDF, EPUB and Kindle. Book excerpt: The word tribology was fIrst reported in a landmark report by P. Jost in 1966 (Lubrication (Tribology)--A Report on the Present Position and Industry's Needs, Department of Education and Science, HMSO, London). Tribology is the science and technology of two interacting surfaces in relative motion and of related subjects and practices. The popular equivalent is friction, wear and lubrication. The economic impact of the better understanding of tribology of two interacting surfaces in relative motion is known to be immense. Losses resulting from ignorance of tribology amount in the United States alone to about 6 percent of its GNP or about $200 billion dollars per year (1966), and approximately one-third of the world's energy resources in present' use, appear as friction in one form or another. A fundamental understanding of the tribology of the head-medium interface in magnetic recording is crucial to the future growth of the $100 billion per year information storage industry. In the emerging microelectromechanical systems (MEMS) industry, tribology is also recognized as a limiting technology. The advent of new scanning probe microscopy (SPM) techniques (starting with the invention of the scanning tunneling microscope in 1981) to measure surface topography, adhesion, friction, wear, lubricant-fIlm thickness, mechanical properties all on a micro to nanometer scale, and to image lubricant molecules and the availability of supercomputers to conduct atomic-scale simulations has led to the development of a new fIeld referred to as Microtribology, Nanotribology, or Molecular Tribology (see B. Bhushan, J. N. Israelachvili and U.

Download or read book Multi Level Methods in Lubrication written by C.H. Venner and published by Elsevier. This book was released on 2000-07-21 with total page 401 pages. Available in PDF, EPUB and Kindle. Book excerpt: Efficient numerical solution of realistic and, therefore, complex equation systems occupies many researchers in many disciplines. For various reasons, but mainly in order to approximate reality, a very large number of unknowns are needed. Using classical techniques, the solution of such a system of equations would take too long, and so sometimes MultiLevel techniques are used to accelerate convergence. Over the last one and a half decades, the authors have studied the problem of Elastohydrodynamic Lubrication, governed by a complex integro-differential equation. Their work has resulted in a very efficient and stable solver. In this book they describe the different intermediate problems analyzed and solved, and how those ingredients finally come together in the EHL solver. A number of these intermediate problems, such as Hydrodynamic Lubrication and Dry Contact, are useful in their own right. In the Appendix the full codes of the Poisson problem, the Hydrodynamic Lubrication problem, the dry contact solver and the EHL solver are given. These codes are all written in 'C' language, based on the 'ANSI-C' version.
