What is Tribology?
Tribology, derived from the Greek word tribos meaning “rubbing,” is the study of interacting surfaces in relative motion. It encompasses the science of friction, wear, and lubrication, forming a critical foundation for understanding and improving the performance and longevity of mechanical systems. Coined in 1966 by Dr. H. Peter Jost, tribology has since become a multidisciplinary field integrating physics, chemistry, materials science, and engineering to address industrial and everyday challenges.
Why is Tribology Important?
Tribology plays a pivotal role in industrial innovation and efficiency. From reducing energy losses in machinery to extending the lifespan of components, tribological advancements have revolutionized industries across eras—from the first industrial revolution to today’s Industry 4.0. As industries demand more sustainable, energy-efficient systems, tribology offers solutions through innovations like advanced lubricants, coatings, and smart tribological systems.
Key Concepts in Tribology
Friction
The resistance to motion between two surfaces.
Wear
The gradual removal or deformation of material due to mechanical action.
Lubrication
The application of substances to reduce friction and wear between surfaces.
