Book Description
Solid Lubricants and Surfaces deals with the theory and use of solid lubricants, particularly in colloidal form. Portions of this book are devoted to graphite and molybdenum disulfides, which are widely used solid lubricants in colloidal form. An extensive literature on the laboratory examination of hundreds of solids as potential lubricants is also provided in this text. Other topics discussed include the metals and solid lubricants; techniques for examining surfaces; other solid lubricants; metal shaping; and industrial uses of solid-lubricant dispersions. This publication is beneficial to equipment designers who know the value of solid lubricants and works engineers interested in the background science underlying solid-lubricant. This text is mainly useful to senior undergraduates who plan to enter the chemical engineering industries.

Book Description
Solid Lubricants and Self-Lubricating Solids provides a concise treatment of solid lubricants and self-lubricating solids and their applications. These solid lubricants include graphite, molybdenum disulfide, plastics and thermoplastics, nylon, soft metals, fluorocarbons, and phenolics. Low-friction inorganic solids as well as miscellaneous inorganic compounds such as dichalcogenides and fluorides are also discussed. This book is comprised of 11 chapters and begins with an overview of some basic facts about friction and lubrication. The reader is then introduced to inorganic solid lubricants, their their crystal structure, advantages and disadvantages, and the forms in which they are most commonly used. The following chapters focus on the lubricating qualities of graphite, molybdenum disulfide, plastics and thermoplastics, nylon, soft metals, and fluorocarbons. Miscellaneous inorganic compounds with special applications involving friction and wear are also considered. The final chapter is devoted to phenolic laminates, their properties, and their mechanical applications such as gears and bearings. This monograph will be a useful resource for designers and operating engineers.

Book Description
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.

Book Description
The process of metalworking by cutting is a complicated technological system consisting of different elements in which the cutting fluid for the lubrication and cooling of the tools is an extremely significant both technological and economic factor. One can influence the reduction of the wear rate in the tools by the lubricant and cooling properties of the cutting fluids. In the extreme conditions of lubrication the application of molybdenum disulfide in the form of suspension in water as a means for lubricating and cooling the tool is theoretically fully justified. Experimentally, the effects of the suspension of molybdenum sulphide has been tested in the milling and sawing processes. Comparative testing has been carried out with the emulsion of cutting oil in water.

Book Description
This chapter focuses attention on the friction and wear properties of selected solid lubricating films to aid users in choosing the best lubricant, deposition conditions, and operational variables. For simplicity, discussion of the tribological properties of concern is separated into two parts. The first part of the chapter discusses the different solid lubricating films selected for study including commercially developed solid film lubricants: (1) bonded molybdenum disulfide (MoS2), (2) magnetron-sputtered MoS2, (3) ion-plated silver, (4) ion-plated lead, (5) magnetron-sputtered diamondlike carbon (MS DLC), and (6) plasma-assisted, chemical-vapor-deposited diamondlike carbon (PACVD DEC) films. Marked differences in the friction and wear properties of the different films resulted from the different environmental conditions (ultrahigh vacuum, humid air, and dry nitrogen) and the solid film lubricant materials. The second part of the chapter discusses the physical and chemical characteristics, friction behavior, and endurance life of the magnetron-sputtered MoS2 films. The role of interface species and the effects of applied load, film thickness, oxygen pressure, environment, and temperature on the friction and wear properties are considered.Miyoshi, KazuhisaGlenn Research CenterTRIBOLOGY; WEAR; SOLID LUBRICANTS; COATINGS; FILM THICKNESS; VACUUM; FRICTION
