Abstract

The tribological behavior of PA66, PA66/Montmorillonite nanocomposites, and PA66/(SEBS-g-MA + Montmorillonite) nanocomposites was studied by means of a ring-on-block tribometer. The morphologies of the worn surfaces of specimens were observed with scanning electron microscopy (SEM). Wear of all of the specimens increases with increasing load; meanwhile, the friction coefficient decreases. Wear of PA66/Montmorillonite is larger than that of PA66. Adding SEBS-g-MA to PA66/Montmorillonite improves the wear resistance. The friction coefficient of PA66/Montmorillonite is slightly less than that of PA66 at various loads. The friction coefficient of PA66/(SEBS-g-MA + Montmorillonite) is the lowest.
