Tribology

Tribology

is the science of friction, lubrication, and wear at the contact faces of surfaces moving relative to each other, and the engineering approaches dealing with them. Wear in its many forms (abrasion, adhesion, cohesion, erosion, and corrosion) imposes significant costs, especially in manufacturing and maintenance. Much recent work in tribology is in biomedicine and surgical implant devices, micro- and nanotechnology in electronics, and wind turbine components (bearings and gears).
