The Handbook of Environmental Degradation of Materials, Third Edition, explains how to measure, analyze and control environmental degradation for a wide range of industrial materials, including metals, polymers, ceramics, concrete, wood and textiles exposed to environmental factors, such as weather, seawater, and fire. This updated edition divides the material into four new sections, Analysis and Testing, Types of Degradation, Protective Measures and Surface Engineering, then concluding with Case Studies. New chapters include topics on Hydrogen Permeation and Hydrogen Induced Cracking, Weathering of Plastics, the Environmental Degradation of Ceramics and Advanced Materials, Antimicrobial Layers, Coatings, and the Corrosion of Pipes in Drinking Water Systems. Expert contributors to this book provide a wealth of insider knowledge and engineering expertise that complements their explanations and advice. Case Studies from areas such as pipelines, tankers, packaging and chemical processing equipment ensure that the reader understands the practical measures that can be put in place to save money, lives and the environment. Introduces the reader to the effects of environmental degradation on a wide range of materials, including metals, plastics, concrete, wood and textiles Describes the kind of degradation that effects each material and how best to protect it Includes case studies that show how organizations, from small consulting firms, to corporate giants design and manufacture products that are more resistant to environmental effects

The effects of materials microstructure on the surface damage mechanism and surface generation is then studied in the third part, focusing on the effect of binder addition. Even though Co and Si can improve the density and toughness of bulk materials, the different mechanical properties between the composition phases and the existence of phase boundaries both contributed to the non-uniform material removal rate and resulted in the formation of reliefs, edge chipping and grain dislodgement. Moreover, the phase transformation induced volume change of Si and the extrusion of Co under the dynamic pressure of the diamond grits lead to the generation of projections on the machined surface. No obvious oxidation of Co and Si occurred for WC/Co and RB-SiC/Si under high spindle speed grinding (HSSG) with minimum quantity lubrication (MQL). In the fourth part, the wear mechanism of the diamond wheel is studied, and its impact on the surface generation is analyzed. The wheel wear mechanism involves rapid loss of the sharp edge, grit splintering, flattening, and oxidation. Two appropriate dressing methods are proposed to obtain a sharp edge on the diamond wheel. With the well prepared wheels, two types of functional surfaces are machined by ultra-precision grinding. The results showed that with the proposed grinding protocol, the form accuracy and surface finish could reach 0.28 Îơm (PV), 9 nm (Ra) for the ÎŒ15 mm TiC based hemisphere couples and 0.64 Îơm (PV), 6 nm (Ra) for the ÎŒ20 mm 'Water-drop' surface on binderless tungsten carbide. The originality and significance of the present research is shown in the following three aspects: (i) new grinding induced surface damage mechanism is identified, including the impact of C segregation, preferred phase growth, etc., so the present research contributes to the understanding of the machining induced surface damage mechanism; (ii) the effects of materials microstructure and wheel wear on the surface characteristics of typical engineering carbides in ultra-precision grinding with a sharp edge wheel are analyzed, and comprehensive knowledge of the surface generation in ultra-precision grinding of brittle materials is achieved; (iii) this study provides clear comprehension on the technique to machine functional surfaces by wheel normal grinding, and it promotes the development of the grinding technology of hard and brittle materials.

Tribology is an unfamiliar term for many, but is experienced by all. It is the science of friction, wear and lubrication of contacting surfaces in relative motion. The aim of this book is to introduce the fundamentals of tribology as well as its challenges in extreme operating conditions. The book comprises a historical background and an introduction to familiarize both undergraduate and postgraduate readers with such an important topic. It addresses a comprehensive coverage of classical tribology of solid contacts, friction mechanics, wear mechanisms and lubrication technologies. The tribology of polymer composites, MEMS and NEMS are explored. In addition, tribology of automotive components is presented, as are tribological applications in many practical situations.Various test methods used in evaluating wear are reviewed. Diverse techniques applied in predicting wear behavior by mathematical models, FE modeling and ANN approach are discussed. The book reviews key features of extraordinary conditions associated with, but not limited to, harsh environments, severe sliding and poor lubrication challenges. A basic understanding of failure modes in tribological systems is covered. The state-of-the-art research on tribology under these extreme conditions is extensively discussed, which will be of interest to researchers. The book highlights solutions for extreme tribology problems and provides an overview of various factors affecting tribosystems in harsh conditions.
