Tribological performance of polyether ether ketone ( PEEK ) subjected to various heat treatments namely, annealing, normalizing, water quenching and oil quenching, respectively, after being heated to a temperature of 250°C is evaluated. It is observed that the different cooling rates have a significant effect on the crystallinity of PEEK which is found to be a governing factor in determining its mechanical and tribological properties. Micro hardness testing and ball‐on‐disk wear test results showed that both hardness and wear resistance increased with an increase in the crystallinity of PEEK . It is observed that the annealed samples showed the highest wear resistance when compared with the water‐quenched samples which is attributed to the increased crystallinity in the case of the annealed samples.
