Wear and Friction of PEEK and CFR-PEEK Materials for Cervical Total Disc Replacement Bearings

摘要

In comparison to the UHMWPE pin-on-plate control, both PEEK on CFR PEEK and CFR-PEEK on PEEK bearing combinations showed poor results in terms of wear. All PEEK and CFR PEEK bearing combinations demonstrated very high friction coefficients, approximately an order of magnitude higher than UHMWPE on CoCr.
