Chapter 5 discusses abrasion, a common wear phenomenon of great economic importance. It has been estimated that 50% of the wear encountered in industry is due to abrasion. Also, it is the mechanism involved in the finishing of many surfaces. Experiments are described to help in understanding the complex abrasion process and in predicting friction and wear behavior in plowing and/or cutting. These experimental modelings and measurements used a single spherical pin (asperity) and a single wedge pin (asperity). Other two-body and three-body abrasion studies used hard abrasive particles.Miyoshi, KazuhisaGlenn Research CenterABRASION; CUTTING; WEAR; SURFACE PROPERTIES; METAL SURFACES; FRICTION; HARDNESS; PARTICLES; GRIT

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

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.

Principles and Applications of Tribology provides a mechanical engineering perspective of the fundamental understanding and applications of tribology. This book is organized into two parts encompassing 16 chapters that cover the principles of friction and different types of lubrication. Chapter 1 deals with the immense scope of tribology and the range of applications in the existing technology, and Chapter 2 is devoted entirely to the evaluation and measurement of surface texture. Chapters 3 to 5 present the fundamental concepts underlying the friction of metals, elastomers, and other materials. The principles of hydrodynamic lubrication are briefly discussed in Chapter 6, and the mechanisms of boundary and elastohydrodynamic lubrication are examined in Chapters 7 and 8. Chapter 9 is a generalized treatise on wear and abrasion phenomena in metals and elastomers, whereas Chapter 10 deals with the internal friction in solids, liquids, and gases. Chapter 11 is an abbreviated yet thorough treatment of experimental methods used in tribological studies. The remaining five chapters in this book are devoted to specific applications, including manufacturing processes, automotive applications, transportation, locomotion, bearing design, and miscellaneous. This book is an ideal source for mechanical engineering students.
