Solid Lubricants and Surfaces by E. R. Braithwaite Pdf
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.

Self-Lubricating Composites by Pradeep L. Menezes,Pradeep K. Rohatgi,Emad Omrani Pdf
In most tribological applications, liquid or grease based lubricants are used to facilitate the relative motion of solid bodies to minimize friction and wear between interacting surfaces. The challenges for liquid lubricants arise in extreme environmental conditions, such as very high or low temperatures, vacuum, radiation, and extreme contact pressure. At these conditions, solid lubricants may be the alternative choice which can help to decrease friction and wear without incorporating liquid lubricants. Challenges with solid lubricants are to maintain a continuous supply of solid lubricants on the contact surfaces to act as lubricous layer between two sliding surfaces. Such a continuous supply is more easily maintained in the case of liquid lubricants when compared to solid lubricants. The most innovative development to ensure a continuous supply of solid lubricant to the contact surface during sliding is to introduce solid lubricant as reinforcement into the matrix of one of the sliding components. Composite materials are engineered or naturally occurring materials which contain two or more distinct constituents with significantly different chemical, physical and mechanical properties. Composites consist of reinforcement and matrix (metal, polymer and ceramics). Among various reinforcements, recent emerging material, solid lubricant, is found to have many favorable attributes such as good lubrication property. Selfâlubrication is the ability of a material to provide lubrication to the contact surface to decrease friction and wear rate in the absence of an external lubricant by transferring embedded solid lubricants in the composite to the interface. Self-lubricating composites (SLCs) are an important category of engineering materials that are increasingly replacing a number of conventional materials in the automotive, aerospace, and marine industries due to superior tribological properties. In SLCs, solid lubricant materials, including carbonous materials, molybdenum disulfide (MoS2), and hexagonal boron nitride (h-BN) are embedded into the matrices as reinforcements to manufacture a novel material with attractive self-lubricating properties. Several studies have been investigated the tribological properties of self-lubricating materials. This book fills that gap to have a reference book about self-lubricating materials and their properties to help scientists, engineers, and industries. This book discusses mechanisms of self-lubricating materials, self-lubricating properties and the applications for industries. The chapters will be written by authoritative expertise in the field. Additionally, this book will demonstrate fundamental study and most advanced innovations in self-lubricating materials as regards to friction and wear. The chapters also include tribological properties of composites and coatings and some practical applications of self-lubricating materials.
Solid Lubricants and Self-Lubricating Solids by Francis J. Clauss Pdf
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.

Testing and Evaluation of Solid Lubricants for Gas Bearings by P. R. Albrecht,W. H. Fischer Pdf
The testing and results of testing solid film lubricants for gas lubricated bearing applications are reported. The tests simulated operational hazards of tilting pad gas bearings. The presence of a low coefficient of friction and the endurance of the solid film lubricant were the criteria for judging superior performance. All solid lubricants tested were applied to a plasma sprayed chrome oxide surface. Molybdenum disulfide and graphite fluoride were the solid lubricants tested; other test parameters included the method of application of the solid lubricant and the surface finish of the plasma sprayed coating. In general, the application of a solid film lubricant was found to significantly improve the coefficient of friction of the rubbing surfaces.
Micro and Nano Sulfide Solid Lubrication by Haidou Wang,Binshi Xu,Jiajun Liu Pdf
"Micro and Nano Sulfide Solid Lubrication" covers the basic principles of sulfide solid lubrication, which is an important field of tribology, an effective means of reducing friction and wear on machine parts, and is closely related to the broader problem of saving energy and materials. This book discusses the low-temperature sulfuration technology which was first developed in China, as well as the two-step methods for preparing various sulfide lubrication films (coatings) created by the authors, which are described in detail. This book is intended for researchers in the fields of tribology, materials science, mechanical design, and structural design. Dr. Haidou Wang and Binshi Xu are both professors at the National Key Laboratory for Remanufacturing, Academy of Armored Forces Engineering, China; Jiajun Liu is a professor at the Department of Mechanical Engineering, Tsinghua University, China.
Lubrication of Electrical and Mechanical Components in Electric Power Equipment by Bella H. Chudnovsky Pdf
Lubrication of Electrical and Mechanical Components in Electric Power Equipment presents an analysis of multiple applications of lubricants in the power industry for both electrical and mechanical parts. One of the key features of this book includes a look at the use of lubricants for surfaces of electrical and mechanical parts protection from mechanical wear and friction. Also included are examples of degradation due to fretting, as well as corrosion protection when lubricant is a barrier between metallic surfaces and atmospheric pollutants. This book analyzes the effects of chemical composition and consistency (fluids, greases, solid lubricants) and the durability of lubricants in regard to various types of contacts and mechanical parts material, design and load. Focused on the importance of carefully choosing the lubricants to maintain a stable contact resistance; preserve the physical integrity of the contact surface; and extend the useful life of mechanical parts, such as bearings, the author presents an exhaustive list of lubricants manufacturers and products recommended for use in the electrical industry.
