Wear behavior of PAEK, poly(aryl-ether-ketone), under physiological conditions, outlooks for performing these materials in the field of hip prosthesis

► Choice of friction couples according to friction coefficient vs. disc wear rate. ► The UHMWPE discs highlight wear rate more than 10 times higher than PAEK discs. ► The ranking of wear rates of polymer materials is: UMHWPE ≫ PEKK, PEKK/CF, PEEK. ► PEEK vs. Co-Cr exhibits the lowest wear rate.
