Tribological Performance of Nylon 6/Montmorillonite Composites

Nylon 6/montmorillonite nanocomposites with different organic montmorillonites was prepared by melt intercalation process.Friction experiments of montmorillonite nanocomposite coupled with 45 steel under dry friction condition were conducted with an M-200 model friction and wear testing machine.The friction coefficient of nylon 6/montmorillonite nanocomposite coupled with 45 steel decreased with the montmorillonite content increase.Wear of nylon 6 and 2% montmorillonite nanocomposite was mainly caused by mechanical wear and viscous friction;Wear of 4% montmorillonite nanocomposite was mainly caused by fatigue action.Wear of 6% and 8% montmorillonite nanocomposites was mainly caused by mechanical wear.Wear of 10% montmorillonite nanocomposite was mainly caused by fatigue action.
