Abrasion Resistance Analysis
Definition - What does Abrasion Resistance Analysis mean?
Abrasion resistance analysis refers to examining the ability of materials and structures to withstand the wearing down or rubbing away of the material by means of friction.
Abrasion resistance helps the material maintain its original structure and appearance. Abrasion resistance resists mechanical wear. Abrasion-resistant materials are useful for both moving and fixed parts in settings where wear is an issue.
The abrasion resistance analysis of materials and structures can be evaluated by a variety of test methods.
Corrosionpedia explains Abrasion Resistance Analysis
Abrasion resistance analysis is used to test the abrasive resistance of solid materials such as metals, composites, ceramics and thick coatings (weld overlays and thermal spray). The intent of this test method is to produce data that will rank materials in the order of their resistance to scratching abrasion under a specified set of conditions. There are two abrasion-analysis testing methods used:
- The standard test method for Measuring Abrasion Using the Dry Sand/Rubber Wheel Apparatus as per ASTM G65. This analysis test is performed by loading a rectangular test sample against a rotating rubber wheel and depositing sand of controlled grit size, composition and flow rate between them. The wheel is rotated in the direction of the flow of sand. The mass of the test sample is recorded before and after conducting a test and the difference between the two values is the resultant mass loss due to dry sand abrasion. To develop a comparison table for ranking different materials with respect to each other, it is necessary to convert this mass loss to volume loss to account for the differences in material densities.
- The standard test method for Pin Abrasion Testing as per ASTM G132. This analysis test is performed using two pin specimens: the subject material and a reference material. A pin is positioned perpendicular to an abrasive surface, which is mounted on and supported by a flat surface. The test machine permits relative motion between the abrasive surface and the pin surface. The wear track of the pin is continuous and non-overlapping. The pin rotates about its axis during testing. The amount of wear is determined by weight loss. The reference specimen wear is included in the calculation in order to correct for abrasivity variations.
Abrasion resistance is related to the compressive strength of concrete. Strong concrete is more abrasion-resistant than weak concrete.
