Wear Resistance. Loss of material from a surface by means of some mechanical action. Wear due to hard particles or hard protuberances forced against and moving along a solid surface. Wear due to localised bonding between contacting solid surfaces leading to material transfer between the two surfaces or the loss from either surface.

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