Wear Behavior of Composites and Nanocomposites: A New Approach

The expulsion of material from either of two strong surfaces in relative movement is termed as wear. Wear can also be defined as surface damage, because of material relocation with no net change in weight or volume. It happens as a natural result and for the most part through surface interactions at severities. It is a system response and is not a material property. Interface wear is firmly commanded by working conditions. Wear can be either desirable or undesirable. Desirable instances of wear incorporate machining, polishing, shearing, and writing with a pencil, whereas undesirable cases incorporate all machine applications, for example, gears, bearings, cams, and seals. At times, it is mistakenly expected that high friction wear implies high wear rates, but this is not valid. Interfaces with solid lubricants and polymers generally indicate low friction, however high wear. On the other hand, ceramics show moderate friction with extremely low wear. In some segregated cases, friction and wear might be corresponded. On an overall basis, friction and wear are two distinct system responses [1].
