The Research on the Friction and Wear Behavior of FKM/NBR Blends under Water Lubrication

Abstract:

In this paper, the friction and wear behavior of FKM, NBR and FKM/NBR blends with the same Shore hardness was investigated in the MPV - 600 wear tester under water lubrication based on the actual working parameters of the screw pump. Wear mechanism of FKM/NBR blends with different load was also analyzed according to their wear loss and frictional coefficient. The results showed that the wear resistance of NBR was improved by the addition FKM. FKM/NBR blend with ratio of 2:8 owned the optimal wear resistance, which was close to that of FKM. The wear of FKM and FKM/NBR blend with ratio of 2:8 was controlled by fatigue wear, and the others were mainly controlled by abrasive wear.
