Design And Fabrication Of Wear Test Measuring Apparatus:- Egemba Joseph C

ABSTRACT

The neglection of friction in most engineering designs has cause more damages due to the inability to ascertain the exact material and the rate at which the material can wear. Wear is defined as damage to a solid surface, generally involving progressive loss of material, due to relative motion between that surface and a contacting substance or surface (Gurumoorthy et al, 2007). Wear is generally described as abrasive, adhesive or erosive (Allen and Ball, 1996). Among these types, abrasive wear is the most important due to its destructive character (Chattopadhyay, 2001). Abrasive wear is the detachment of the material from surfaces in relative motion, caused by sliding of hard particles between the opposing surfaces; the hard particles normally slide on a softer surface and detach materials from the latter (Harris et al, 2002).
