Introduction




Friction and wear of materials are two phenomena that affect almost every aspect of engineering and science. Friction is the resistance to relative motion between two surfaces in contact. Wear is the progressive loss or damage of material due to friction or other causes. Both friction and wear can have significant impacts on the performance, efficiency, reliability, safety, and cost of machines, devices, structures, or systems.


The author of this book is Ernest Rabinowicz (1919-2006), who was a professor emeritus at MIT and a pioneer in tribology (the study of friction, wear, lubrication). He wrote this book in 1965 based on his extensive research and teaching experience in this field. He revised it in 1995 to include new developments and applications.


The main purpose of this book is to provide a lucid presentation of the theory of mechanical surface interactions. The book covers both fundamental principles and practical aspects of friction and wear of materials. The book is organized into eight chapters, each of which deals with a specific topic or aspect of friction and wear of materials. The book also includes an appendix with sample problems and an index.


Summary




In this section, I will briefly describe the main topics and concepts covered in each chapter of the book.


Chapter 1: Material Properties That Influence Surface Interactions




This chapter introduces the material properties that influence surface interactions, such as hardness, roughness, elasticity, plasticity, strength, toughness, ductility, brittleness, etc. The chapter explains how these properties affect the deformation, fracture, and wear of materials. The chapter also discusses some methods and techniques for measuring these properties.


Chapter 2: Surface Interactions




This chapter explains the different types of surface interactions that occur when two surfaces are in contact, such as adhesion, abrasion, corrosion, fatigue, etc. The chapter describes the mechanisms and effects of these interactions on the friction and wear of materials. The chapter also introduces some models and theories for analyzing these interactions.


Chapter 3: Friction




This chapter discusses the various factors that affect friction, such as load, speed, temperature, lubrication, etc. The chapter defines different types of friction, such as static friction, kinetic friction, rolling friction, sliding friction, etc. The chapter also presents some laws and equations for calculating friction, such as Coulomb's law, Amontons' law, Bowden and Tabor's equation, etc.


Chapter 4: Types of Wear




This chapter distinguishes between the different types of wear that can occur due to friction or other causes, such as adhesive wear, abrasive wear, corrosive wear, fretting wear, etc. The chapter explains the mechanisms and characteristics of each type of wear. The chapter also provides some methods and criteria for measuring and evaluating wear.


Chapter 5: Adhesive Wear




This chapter focuses on adhesive wear, which is the most common type of wear that occurs due to friction. Adhesive wear is caused by the formation and rupture of microscopic bonds or junctions between two surfaces in contact. The chapter describes the factors that influence adhesive wear, such as material properties, surface conditions, contact geometry, load, speed, temperature, etc. The chapter also presents some models and equations for estimating adhesive wear, such as Archard's equation, Rabinowicz's equation, etc.


Chapter 6: Abrasive and Other Types of Wear




This chapter covers abrasive and other types of wear that can occur due to friction or other causes. Abrasive wear is caused by the removal of material by hard particles or protuberances on one or both surfaces in contact. Other types of wear include corrosive wear (caused by chemical or electrochemical reactions), fretting wear (caused by small oscillatory motions), erosive wear (caused by impingement of solid or liquid particles), cavitation wear (caused by formation and collapse of bubbles), etc. The chapter explains the mechanisms and factors that affect these types of wear. The chapter also suggests some ways to reduce or prevent these types of wear.


Chapter 7: Lubrication




This chapter illustrates how lubrication can reduce friction and wear by forming boundary layers or fluid films between two surfaces in contact. Lubrication can be classified into three regimes: boundary lubrication (where the surfaces are separated by a thin layer of adsorbed molecules), hydrodynamic lubrication (where the surfaces are separated by a thick layer of viscous fluid), and elastohydrodynamic lubrication (where the surfaces are separated by a thin layer of pressurized fluid). The chapter describes the principles and characteristics of each regime. The chapter also discusses some properties and types of lubricants.


Chapter 8: Adhesion




Chapter 8: Adhesion




This chapter analyzes how adhesion can influence friction and wear by creating cold welding, junction growth, plowing, etc. Adhesion is the tendency of two surfaces to stick together due to molecular or atomic forces. The chapter describes the factors that affect adhesion, such as surface energy, roughness, contamination, temperature, etc. The chapter also presents some models and theories for calculating adhesion, such as Johnson-Kendall-Roberts theory, Derjaguin-Muller-Toporov theory, etc.
