Tribology Fundamentals: Friction, Wear, and Lubrication

Mechanical systems lose massive amounts of energy and experience premature failure due to friction and wear. Understanding the science of interacting surfaces is key to engineering efficient, long-lasting machinery. This text-based course provides a clear pathway to mastering the core principles of surface engineering, lubrication, and wear prevention. You will learn to analyze complex surface interactions, select appropriate lubricants, and diagnose wear mechanisms to optimize mechanical performance. What you'll learn: Understand the fundamental principles of surface roughness, contact mechanics, and friction theories; Identify different wear mechanisms, including adhesive, abrasive, fatigue, and corrosive wear; Evaluate lubrication regimes, from hydrodynamic and elastohydrodynamic to boundary lubrication; Analyze modern synthetic lubricants, additives, and eco-friendly green tribology practices; Apply tribological principles to the design and maintenance of bearings, gears, and seals. The course begins with foundational definitions of surface topography and contact mechanics before progressing to practical friction theories, wear analysis, and advanced lubrication strategies. Designed for beginner engineers, maintenance technicians, and students of mechanical engineering, this course requires no prior specialized knowledge of surface science.
