In the 1970s and the early 1980s there was an enormous volume of research and development into the subject of molybdenum disulphide lubrication, much of which was supported by national governments for the benefit of defence, aviation or space activities. There were already some well-established practical guidelines for deciding when and how to use molybdenum disulphide, but there was still a considerable lack of universally-accepted theoretical understanding of some of the important and fundamental aspects of molybdenum disulphide technology. However, the state of knowledge was growing rapidly. In the past fifteen years the situation with regard to the technology of molybdenum disulphide lubrication has stabilised in many respects, and a measure of consensus has been reached about some of the mechanisms involved. The use of molybdenum disulphide has become routine in some industries, and there are many well-established and reputable commercial products available. Except in the high-technology field of physical deposition techniques, especially sputtering, the output of new research publications has fallen from perhaps two hundred a year in the 1970s to fewer than ten a year in the 1990s. In spite of this maturing of the subject, it is clear that there are still many aspects in which disagreements persist about the mechanisms involved, and which as a result are unclear or misunderstood among current, and perhaps even more importantly, potential users. One of the primary objectives of this book is to analyse the various aspects of molybdenum disulphide lubrication technology about which there are still disagreements or controversy, and to attempt to come to firm conclusions about some of the mechanisms involved. In particular, it will place emphasis on the importance and effects of burnishing and film consolidation.

Despite their efforts, industries continue to lose millions of dollars every year to the destructive effects of corrosion on both structures and equipment. A large part of the problem is that diagnosing its causes and developing strategies to avoid corrosion depend on the application of principles drawn from a broad spectrum of physical sciences not typically encountered in engineering and other technical disciplines associated with industrial production. While continuing to fully explain the basic principles needed to understand corrosion science, this new edition of Corrosion Science and Technology has been updated and expanded to present the very latest technologies and strategies for limiting costly metal degradation caused by corrosion. Written by respected experts who possess an understanding of the sciences involved as well as experience with the development of corrosion control methods, this volume describes the chemistry, electrochemistry, physics, and metallurgy of various types of metals, and evaluates numerous protection measures and surface treatments. New to the Second Edition • New chapters that examine the corrosion resistance of copper, nickel, titanium, and their respective alloys • An entire chapter devoted to the expanded discussion of cathodic protection by impressed current and sacrificial anodes • Extended coverage of the equipment used in the medicine, power generation, and marine environments • Additional case histories and recently employed real-world applications Exploring corrosion control methods used in an expanded variety of commercial enterprises including aviation, automobile manufacturing, food processing, and building construction, this practical guide presents proven and cost-effective methods that industrial engineers can call upon to better protect material assets.
