Abrasion Testing Explained
Other conditions that contribute to visible wear include cleaning, wiping, rubbing, shipping, storage, and accidental damage. RCA abrasion testing (ASTM F2357) allows for the determination of the amount of visible wear on a material by subjecting inks and coatings to a repeated, abrasive force.

Abrasive Wear
Abrasive wear is a classic wear mechanism, causing damage to the bearing surfaces of artificial joints by abrasion and producing large quantities of bioactive wear debris. It is a very common phenomenon when the rough surface, which is made from hard materials, slides against a relatively soft countersurface [85].In this case, millions of asperities on the harder surface …
Friction and Wear
An important issue with these tests is that, as abrasion of the test sample takes place, the abrasive paper degrades by clogging with wear debris and due to damage to the contacting regions of the abrasive particles, so that the wear of the test sample will typically decrease as the test progresses; in extreme cases the wear mechanism may ...

Abrasion Testing
Taber abrasion testing (ASTM D4060) is performed by mounting a flat specimen, typically under 0.25" thickness, to a rotating platform that contacts standard abrasive wheels at fixed speed and pressure. The abrasive wheels provide contact wear to the specimen for the duration of the test, typically 1,000 to 10,000 cycles.
