1.1 Definition of tribology “Tribology” is derived from the Greek word ‘tribos’ meaning rubbing or sliding. It is the study of rubbing or sliding. Tribology focuses on friction , wear and lubrication of interacting surfaces in relative motion (1967) Tribology is an applied art and as such should be based upon, or requires background knowledge, in many topics. In mechanical engineering (the seat of most design instruction): Fluid mechanics , Elasticity, 5
