An abrasion test measures a material’s resistance to wear from sliding contacts. Factors considered when selecting a test include contact area shape, surface composition, sliding speed, force, duration, and environment. Tests can vary, and results can be measured in terms of material lost or cycles before failure. Standardized tests are often used for cost-cutting and accurate comparisons.
An abrasion test is a test used to measure the resistance of a material to wear resulting from sliding contacts such as rubbing, grinding or scraping against another material. An abrasion test can also be referred to as a wear test, an abrasion test, or simply an endurance test. Wear tests are of interest in a number of technical fields, including civil and mechanical engineering, reliability engineering, metallurgy, and geology. These tests are important to ensure the life of a material in a particular product or application, and to ensure that material that erodes through abrasion does not cause safety or environmental hazards in production or test environments or in product use. product.
Several factors are usually considered when 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 that come into contact with each other. One can also consider the sliding speed between the two surfaces, the force with which they act on each other and the duration of contact between them. In addition to the materials themselves, the environment they come into contact with also plays a role in selecting an appropriate abrasion test.
Wear testing can take many forms, depending on these factors. For example, the abrasion resistance of fabric could be tested by rubbing one fabric against another fabric for a given number of cycles to simulate the abrasion that might occur in the waist of a pair of pants. A test in which samples are loaded into a beaker which is rotated for a set number of cycles could be used to test the surface wear of charcoal briquettes during transport and handling. The test equipment used will depend on the abrasion test selected, as well as the size and material composition of the items to be tested.
Abrasion can be measured in a variety of ways, depending on the strength test used and the desired information from the test. For example, if the amount of material lost is an issue whether or not the material fails, abrasion can be measured in terms of the percentage of material lost, by mass or volume, between the start and end of the test . Another measure sometimes used is the number of abrasion cycles a material will withstand before failure. This would be more appropriate if information about how long the material or product will survive before total failure is of primary interest.
Surface wear can be tested on a variety of materials and products, including rope, concrete, iron ore, paint, ceramic tile, and footwear. While custom tests can be developed, standardized tests developed for a particular industry, material, or product are often used as a cost-cutting measure or to make accurate comparisons between test samples. Different technical organizations maintain abrasion testing standards for their specific industries.
