Fundamentals of Tribology: Friction, Wear, and Lubrication

Every moving machine part is subject to the forces of friction, wear, and lubrication, making tribology one of the most critical fields in modern engineering. Understanding these surface interactions is key to preventing mechanical failure and optimizing system performance. This text-only course provides a clear foundation in tribology, guiding you from basic surface physics to advanced modern applications. You will learn how to analyze surface roughness, select the right lubricants, and implement strategies to minimize energy loss and component wear. What you'll learn: 1. Understand the core principles of friction, surface contact, and adhesion. 2. Identify different types of wear, including abrasive, adhesive, and corrosive wear. 3. Categorize lubrication regimes from boundary lubrication to hydrodynamic lubrication. 4. Apply modern green tribology concepts to select environmentally friendly lubricants. 5. Analyze real-world component failures in bearings, gears, and seals through surface inspection principles. The material transitions from fundamental definitions of surface roughness and contact mechanics to practical strategies for lubricant selection and wear prevention, ending with an introduction to sustainable engineering practices. This course is designed for mechanical engineering students, practicing engineers, and technicians who are new to tribology and want a solid foundational understanding without complex prerequisites.
