wear and corrosion

Wear - Wikipedia

Wear is the damaging, gradual removal or deformation of material at solid surfaces.Causes of wear can be mechanical (e.g., erosion) or chemical (e.g., corrosion).The study of wear and related processes is referred to as tribology.. Wear in machine elements, together with other processes such as fatigue and creep, causes functional surfaces to degrade, eventually leading to material failure or ...
