Introduction to Tribology

What does "Tribology" mean?

Tribology came from the Greek word, “tribos”, meaning “rubbing or “to rub”
And from the suffix, “-ology” means “the study of”
Hence, “Tribology” is the study of rubbing, or… “the study of surfaces that rub together.”

Tribology is defined as the science and engineering of surface phenomena such as friction, wear and lubrication etc.

Tribological design and materials selection play vital roles in the performance, operation and durability of all mechanical machines. Even our body faces tribological issues and problems especially in joints.
