Talking about Taber Abrasion Testing

Talking about Taber Abrasion Testing

Taber Abrasion is a quick and inexpensive procedure, designed to compare the wear rate and mass-loss of one or more material or coatings. A typical Taber abrasion test consists of a disk-shaped specimen that is placed in constant contact with an abrasive wheel, using predetermined forces to a specified number of cycles to determine wear. The most commonly used standards for these tests are: ASTM D4060, ASTM F1978-12 and MIL-A-8625.Qinsunlab  frequently recommends Taber abrasion as a quick and simple way to measure wear resistance and offer sufficient comparable data at a reasonable price. It gives a side by side comparison of several materials or coatings, so you can evaluate which material has better wear resistance under simulated, accelerated wear conditions.
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.
