Introduction to Tribology: Friction, Wear, and Lubrication Design

Every moving machine, from micro-sensors to heavy industrial gearboxes, relies on the principles of tribology to function efficiently and avoid catastrophic failure. This comprehensive text-only course introduces you to the science of interacting surfaces in relative motion, giving you the tools to analyze and minimize friction and wear. You will transition from understanding basic surface contact to designing robust, low-friction systems that stand the test of time. What you'll learn: - Understand the core physical and chemical characteristics of engineering surfaces - Analyze friction and wear mechanisms across metals, polymers, and ceramics - Apply boundary and solid-film lubrication principles to reduce mechanical energy loss - Compare nano-tribological behavior with macro-scale engineering applications - Diagnose common failure modes like abrasive wear, delamination, and surface fatigue - Explore modern sustainability concepts including green lubricants and energy-efficient surface texturing This course begins with foundational definitions of surface roughness, contact mechanics, and the laws of friction. You will then progress through detailed modules covering wear modes, lubrication regimes, and real-world engineering diagnostics. Designed specifically for beginners, this course requires no prior background in advanced materials science or fluid dynamics.
