摘要：
To study the fretting tribological behavior of a PEEK hip prosthesis, Ti6Al4V was used as the stem taper material, PEEK was used as the head material, and CoCrMo was used as the contrast material for the PEEK. Fretting friction and wear experiments between the stem taper and head were carried out to demonstrate the feasibility of PEEK as a metal substitute. The results show that the wear values of the Ti6Al4V/PEEK and Ti6Al4V/CoCrMo pairs were all of a small order of magnitude. The Ti6Al4V/PEEK pairs had a better corrosion resistance than the Ti6Al4V/CoCrMo pairs. Meanwhile, the fretting characteristics and damage mechanism of the Ti6Al4V/PEEK pairs were obtained.
