Synopsis Lubrication Degradation Mechanisms by : Sanya Mathura
In industry, owners, engineers and workers have struggled with lubricant degradation and its effects on their equipment. The purpose of Lubrication Degradation Mechanisms: A Complete Guide is to help personnel to understand the reasons behind the degradation of their lubricant, determine methods to identify the onset of degradation and reduce or eliminate lubricant degradation within their equipment. One of the most common forms of lubricant degradation is oxidation. However, this is not the only method by which a lubricant degrades. By understanding the differences between degradation patterns, personnel can employ specific tasks / tests to aid in their identification of the type of degradation and the factors responsible. The aim of this book is to educate facility personnel on the methods of degradation and ways in which it can be reduced or eliminated while keeping an eye on the cost of operation.

Synopsis Polymer Degradation and Stabilization by : W. L. Hawkins
The development of polymers as an important class of material was inhibited at the first by the premature failure of these versatile compounds in many applications. The deterioration of important properties of both natural and synthetic polymers is the result of irreversible changes in composition and structure of polymers molecules. As a result of these reactions, mechanical, electrical and/or aesthetic properties are degraded beyond acceptable limits. It is now generally recognized that stabilization against degradation is necessary if the useful life of polymers is to be extended sufficiently to meet design requirements for long-term applications. Polymers degrade by a wide variety of mechanisms, several of which affect all polymers through to varying degree. This monograph will concentrate on those degradation mechanisms which result from reactions of polymers with oxygen in its various forms and which are accelerated by heat and/or radiation. Those stabilization mechanisms are discussed which are based on an understanding of degradation reaction mechanisms that are reasonably well established. The stabilization of polymers is still undergoing a transition from an art to a science as mechanisms of degradation become more fully developed. A scientific approach to stabilization can only be approached when there is an understanding of the reactions that lead to degradation. Stabilization against biodegradation and burning will not be discussed since there is not a clear understanding of how polymers degrade under these conditions.

Synopsis Mechanisms of Polymer Degradation and Stabilisation by : G. Scott
The purpose of this publication is two-fold. In the first place it is intended to review progress in the development of practical stabilising systems for a wide range of polymers and applications. A complemen tary and ultimately more important objective is to accommodate these practical developments within the framework of antioxidant theory, since there can be little question that further major advances in the practice of stabilisation technology will only be possible on a firm mechanistic foundation. With the continual increase in the number of commercial anti oxidants and stabilisers, often functioning by mechanisms not even considered ten years ago, there is a need for a general theory which will allow the potential user to predict the performance of a particular antioxidant structure under specific practical conditions. Any such predictive tool must involve a simplified kinetic approach to inhibited oxidation and, in Chapter 1, Denisov outlines a possible mechanistic approach with the potential to predict the most useful antioxidant to use and the limits of its usefulness. In Chapter 2, Schwetlick reviews the current state of knowledge on the antioxidant mechanisms of the phosphite esters with particular emphasis on their catalytic peroxidolytic activity. Dithiophosphate v vi PREFACE derivatives show a similar behaviour but for quite different reasons and, in Chapter 3, AI-Malaika reviews information available from analytical studies, particularly using 31p_NMR spectroscopy, to elucid ate the complex chemistry that leads to the formation of the antioxidant -active agents.

Synopsis Structure Design and Degradation Mechanisms in Coastal Environments by : Abdelkarim Ait-Mokhtar
This book provide a series of designs, materials, characterization and modeling, that will help create safer and stronger structures in coastal areas. The authors take a look at the different materials (porous, heterogeneous, concrete...), the moisture transfers in construction materials as well as the degradation caused by external attacks and put forth systems to monitor the structures or evaluate the performance reliability as well as degradation scenarios of coastal protection systems.

Synopsis Mechanisms of Chemical Degradation of Cement-based Systems by : K.L. Scrivener
Deterioration of cement-based materials is a continuing problem, as it results in the substantial shortening of the lives of conventional concrete structures. The main costs result from poor performance and the need for early repair. With more advanced applications, where very long service lives are essential, such as the storage of nuclear waste, an understanding of the degradation processes in order to predict long term performance is very important. this book forms the proceedings of the latest Symposia at the Materials Research Society Autumn meeting in Boston.
