Abrasive wear is particles or abrasive material with either sliding, erosion or impact wear or a combination of these. Surface fatigue is a specific wear of components with high surface pressure levels, e.g. rails and bearings. 3. What influences wear of steel? The hardness of the steel and of the abrasive have the biggest influence.

13.1.1.1 Pin-on-disk. Pin-on-disk wear test is carried out according to the ASTM G 99 standards [2]. Parameters used in pin-on-disk are load, sliding velocity, and sliding distance. Fig. 13.1 shows the pin-on-disk apparatus. The pin-on-disk tests are preferably used to determine two-body sliding wear. In pin-on-disk, the pin is attached with ...
