Abstract We studied the effect of temperature on the friction‐wear properties of poly(ether ketone) with a cardo group (PEK‐C) with a XuanWu‐3 pin‐disc friction‐and‐wear tester. Testing conditions such as the temperature obviously affected the friction and wear behavior of PEK‐C. As the ambient temperature increased, the wear of PEK‐C increased, and there was a maximum value of the friction coefficient of PEK‐C at a certain temperature. This phenomenon could be attributed to the effect of an adhesive–elastic property of PEK‐C. Scanning electron microscopy revealed that the size and shape of the wear debris of PEK‐C varied as the temperature varied. The main mechanism behind the different tribological characteristics lay in the variations of the physical state on the friction surface of PEK‐C due to the increasing surface temperature of PEK‐C. © 2004 Wiley Periodicals, Inc.
