Available in PDF, EPUB and Kindle. Book excerpt: This research conducts tribological investigation in three areas. The first area of research is to obtain basic understanding of tribological properties of high performance Inconel alloys. Pin-on-disk testing was conducted through a range of applied normal loads and sliding velocities in an unlubricated condition. Average friction coefficient, friction work, and specific wear rates were calculated from the data and microscopy techniques were used to observe and characterize wear mechanisms. Experimental results show a dependence of average coefficient of friction as a function of frictional work. Also shown is the wear rate dependence on frictional work, predicated by a wear mechanism change. This research gives a tribological baseline for high performance alloys. The second area of research is in the in situ spatial study of friction, complemented by monitoring changes in electrical contact resistance (ECR). Pin-on-disk testing of samples was done under low normal loads and velocities. Friction and electrical contact resistance measurements were taken spatially in the wear track during each friction cycle, giving a spatial evolution of friction and resistance change, in situ. Results show a lowering in the ECR under increased friction cycles, which was closely related to a change in the friction coefficient of the material. Using surface profilometry and X-ray Photoelectron Spectroscopy, we determined that the lowering of resistance is a result of surface modification through wear and development of a friction induced conductive tribo-film. This research provides a simple method for in situ monitoring of friction and solidifies a fundamental relationship between friction and contact resistance. The third area of research is the design of a variable force tribometer, incorporating the fundamental results demonstrated in the first two experiments. The creation of a novel testing apparatus to test materials under dynamic tribological conditions is given in detail. Simple experiments were performed on an Inconel sample and preliminary results show how dynamic normal and tangential forces affect the friction coefficient. These early results utilizing the variable force tribometer will lay the groundwork for more advanced research into the dynamic nature of friction.

Available in PDF, EPUB and Kindle. Book excerpt: TRIBOLOGY AND CHARACTERIZATION OF SURFACE COATINGS The book provides updated information on the friction and wear behavior of coatings used in various industrial applications. Surface modification is a cost-effective process of increasing the life of components so that the whole device need not be changed if the surface is worn out. The tribological behavior of biological implants is currently an active topic and a thorough discussion is one of the book’s features. Tribology and Characterization of Surface Coatings explores key issues which are important in the research and development of surface coatings by providing updated information on friction and wear behavior of coatings used in different industrial applications. It covers the various coating deposition techniques, tribological response of nanocomposite coatings, multilayer hardfacing, and wear testing methods for coatings at nanoscale. The use of nanostructures may alter the tribological, characterization, and mechanical properties of the materials. Thermal spraying is the most widely used technique in industry for the deposition of coatings and their tribological properties need to be determined. This book also includes the recent trends in biotribology and the materials used in implants to counter the abrasive wear. Audience The book will serve as a reference to researchers, scientists, academicians, industrial engineers, and students who work in the fields of materials/polymer science and mechanical engineering.

Download or read book Tribology Materials Characterization and Applications written by Bernice Wyong and published by . This book was released on 2020-09-15 with total page 193 pages. Available in PDF, EPUB and Kindle. Book excerpt: The engineering and science of interacting surfaces in relative motion is known as tribology. It studies and applies the principles of friction, wear and lubrication. Tribology is an interdisciplinary field which draws upon other disciplines such as physics, materials science, biology, engineering, chemistry and mathematics. The fundamental concepts of tribology include tribosystem, tribofilm and stribeck curve. Tribosystem is useful in providing a comprehensive assessment of the important outputs, inputs and losses to tribological systems. Tribofilms are layers which form upon surfaces that are tribologically stressed, and reduce friction and wear in the tribological systems. The stribeck curve is used to understand how the friction in fluid-lubricated contacts is a non-linear function of lubricant viscosity, contact load and entrainment velocity. The topics included in this book on tribology are of utmost significance and bound to provide incredible insights to readers. This book consists of contributions made by international experts. It will help the readers in keeping pace with the rapid changes in this field.

Download or read book Properties and Characterization of Modern Materials written by Andreas Öchsner and published by Springer. This book was released on 2016-07-30 with total page 450 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book focuses on robust characterization and prediction methods for materials in technical applications as well as the materials’ safety features during operation. In particular, it presents methods for reliably predicting material properties, an aspect that is becoming increasingly important as engineering materials are pushed closer and closer to their limits to boost the performance of machines and structures. To increase their engineering value, components are now designed under the consideration of their multiphysical properties and functions, which requires much more intensive investigation and characterization of these materials. The materials covered in this monograph range from metal-based groups such as lightweight alloys, to advanced high-strength steels and modern titanium alloys. Furthermore, a wide range of polymers and composite materials (e.g. with micro- and nanoparticles or fibres) is covered. The book explores methods for property prediction from classical mechanical characterization-related fields of application, for example, from wear, creep, fatigue and crack growth, to specific surface properties, to dielectric and electrochemical values. As in all fields of modern engineering, the process is often accompanied by numerical simulation and optimization.

Download or read book Tribology written by Thanh Phuc Van and published by . This book was released on 2010-08-01 with total page 320 pages. Available in PDF, EPUB and Kindle. Book excerpt: "In the past decades, significant advances in tribology have been made as engineers strive to develop more reliable and high performance products. The advancements are mainly driven by the evolution of computational techniques and experimental characterization that leads to a thorough understanding of tribological process on both macro- and microscales. Tribology comprises the fields of friction, wear and lubrication. It aims at the functional, economical and ecological optimization of motion systems. The implementation of tribological knowledge results in a reduction of wear and an optimization of friction systems. The operational reliability of machines and installations is increased, production costs are reduced, resources and energy are saved and emissions are decreased. Tribology is particularly important in today's world because so much energy is lost to friction in mechanical components. To use less energy, we need to minimize the amount that is wasted. Significant energy is lost due to friction in sliding interfaces. Therefore, finding ways to minimize friction and wear through new technologies in tribology is critical to a greener and more sustainable world. Tribology - Lubricants and Lubrication present comprehensive overview on recent progress on the hydrodynamic lubrication analysis and the lubrication tests for biodegradable lubricants.
