Abrasion resistance is the ability of a fabric to withstand surface wear from rubbing.The purpose of abrasion test is to evaluate the strength of the aggregate in order to give a clear overview about the tested material.Abrasion testing is used to test the abrasive resistance of solid materials. Materials such as metals, composites, ceramics, and thick (weld overlays and thermal spray) coatings can be tested with these methods. The intent of abrasion testing is to produce data that will reproducibly rank materials in their resistance to scratching abrasion under a specified set of conditions.
Abrasion tests are all subject to variation due to changes in the abradant during specific tests. The abradant must be changed accordingly at frequent intervals or checked periodically against a standard. With disposable abradants, the abradant is used only once or changed after limited use. With permanent abradants that use hardened metal or equivalent surfaces, it is assumed that the abradant will not change appreciably in a specific series of tests, but obviously similar abradants used in different laboratories will not likely change at the same rate due to differences in usage.
Abrasion resistance testing is of interest in a number of technical fields, including civil and mechanical engineering,reliability engineering, metallurgy, and geology. These tests are of importance in ensuring the durability of a material in a particular product or application,and in ensuring that material that erodes because of abrasion does not cause environmental or safety hazards in the production or test environments or in use of the product.
Several factors are typically considered in developing or selecting an appropriate abrasion test for the application at hand.The shape of the contact area is taken into consideration, as is the composition of the two surfaces making contact with one another. Speed of sliding contact between the two surfaces, the force with which they act on one another,and the duration of contact between them may also be considered. In addition to the materials themselves, the environment in which they are making contact also plays a role in selecting an appropriate abrasion test.
