Abstract

Some form of wear takes place with nearly all real mechanical items. Wear may physically be a phenomenon corresponding to the colloquial use of the term in which material is worn away so that clearances or stresses become too great for satisfactory use. It may additionally be due to physical or chemical deterioration, to ageing, or to corrosion, erosion and so forth. Alternatively, wear may be due to fatigue of the material leading to failure, or to creep leading to loss of clearance or possibly rupture. The term ‘wear-out’ thus embraces a wide variety of phenomena, the common feature being a reduction of any failure-controlling strength attribute of the component with time.
