Wear

Other Names:
Wear and tear
Erosion of metals
Nature:

Wear is the removal of material from a solid surface as the result of mechanical action exerted by some other solid, possibly in the form of particles or as a result of the action of strong gas or liquid currents upon a surface, especially at high temperatures. Any sliding contact between solids leads to a measurable, if small, material loss. Such losses are particularly serious in modern precision mechanisms, for if they persist they lead rapidly to mechanical failure.
