Tribological Performance of Nylon Composites with Nanoadditives for Self-Lubrication Purposes

A systematic study comparing the wear behaviour of composites with nylon matrix (PA66, PA46, PA12) and different nanoadditives and reinforcing additives (graphite, graphene, MoS(2) and ZrO(2)) has been carried out in order to achieve a proper self-lubricant material for bearing cages. The wear chara...

Sumario:A systematic study comparing the wear behaviour of composites with nylon matrix (PA66, PA46, PA12) and different nanoadditives and reinforcing additives (graphite, graphene, MoS(2) and ZrO(2)) has been carried out in order to achieve a proper self-lubricant material for bearing cages. The wear characterisation was done using pin-on-disc tests, SEM and EDX analysis. The results show that better outcomes are obtained for composites based on PA12. The addition of ZrO(2) offers negative values of wear due to the metallic particle transference from the counterface to the polymeric pin.
