Universidad de Zaragoza (orcid)0000-0003-4230-7900 Analysis of self-lubrication enhancement via PA66 strategies: Texturing and nano-reinforcement with ZrO2 and graphene 2019 Graphene nanoflakes and zirconium dioxide (ZrO2) were added to polyamide 66-based composites with glass fibre in order to improve their self-lubricating properties and make them suitable for high-performance bearing applications. The influence of texturing the surfaces was also investigated. The tribological behaviour was analysed for different combinations of hybrid polymeric composites, percentages of additive, and texturing geometries. The results show that the lowest low friction coefficients are obtained for PA66 + 30GF with 5% graphene. Worn surfaces, analysed by scanning electron microscopy and optical microscopy confirm the enhancement of the tribological properties with the addition of graphene. Texturing results under dry lubrication are not relevant for tribological purposes.
