| Abstract: | The tribological properties of poly(ether–ether–ketone) (PEEK)/aluminum nitride (AlN) composites reinforced with micro‐ and nano‐AlN particles were evaluated under dry sliding conditions. The wear resistance of pure PEEK is 10‐fold higher than mild steel. It was further improved by 2‐fold at 20 wt % micro‐AlN and by more than 4‐fold at 30 wt % nano‐AlN composite compared with pure PEEK. The improvement in wear resistance was attributed to a thin and coherent transfer film. However, it was deteriorated on further increasing micro‐AlN. The coefficient of friction of the composites was increased. Scanning electron microscopy and optical microscopy of worn surfaces and transfer films have been explained in detail. © 2011 Wiley Periodicals, Inc. J Appl Polym Sci, 2011 |
