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 …

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.
