The Measurement Of Abrasion Resistance

2017-11-17 15:03
The measurement of abrasion resistance, usually by the weighing of a material sample before and after subjecting 
it to aknown abrasive stress throughout a known time period, or by reflectance or surface finish comparisons, 
or by dimensional comparisons.
An abrasion test is a test used to measure the resistance of a material to wear stemming from sliding contact
such as rubbing, grinding, or scraping against another material. An abrasion test may also be referred to as
wear testing, as an abrasion resistance test, or simply as a resistance test. Wear 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.
