Investigations on the influence of molybdenum disulphide on tensile and dry sliding wear characteristics of nylon 66/carbon black composites

摘要

The sliding tensile and dry sliding wear behaviours of nylon 66/1 wt.% carbon black composites with varying amounts viz., 0.5, 1, 2 and 3 wt.% of molybdenum disulphide (MoS_2) have been studied. The wear behaviour of nylon 66/carbon black/MoS_2 composites has been investigated using pin-on-disc tester under dry condition. Wear characteristics have been measured at different sliding velocity, loads and sliding distances. The coefficient of friction of the composites increases with increase in normal load due to changes in the area of contact. Wear mechanisms were established using SEM.
