Abrasion & Wear Testing

Author: Released in:2020-08-06 Click:67

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.

We offer various abrasion and wear test methods, and can assist in choosing the best method for your project. Our engaged experts work diligently to help make certain your materials are safe, quality, compliant and fit for purpose.

abrasion test methods
Element’s material testing engineers perform fast, repeatable testing to help you predictively rank your materials in a similar relative order of merit as would occur in an abrasive environment.

Pin abrasion (ASTM G132) 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 pin abrasion testing machine permits relative motion between the abrasive surface and the pin surface.
Rubber wheel abrasion (ASTM G65) 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.
Taber abrasion (ASTM D1044, ASTM D4060, and others) is performed by mounting a flat specimen, either square or round, to a turntable platform that rotates two abrasive wheels over the specimen at a fixed speed and pressure.
Falling sand abrasion (ASTM D968) is used to determine the resistance of organic coatings to falling sand. The coatings are typically applied to a plane rigid surface, like glass or metal, before testing.
RCA abrasion (ASTM F2357) is performed using a Norman Tool Machine. Inks and coatings on printed membrane switches are affected by repeated abrasive forces, most commonly by a human finger. Other conditions that contribute to visible wear include cleaning, wiping, rubbing, shipping, storage, and accidental damage.
