| Abstract: | The effect of normal load and sliding speed on the tribological properties of a thin film of ultra-high-molecular-weight polyethylene (UHMWPE) coated onto a polyether ether ketone (PEEK) substrate sliding against a stainless steel ball in dry conditions are investigated. Wear tests are carried out with a ball-on-disc configuration to evaluate the tribological properties of the plasma-treated PEEK samples coated with UHMWPE film at different normal loads (5, 7, and 9 N) and linear speeds (0.1, 0.2, and 0.5 m/s). The coated samples exhibited a very low coefficient of friction of ～0.09 compared to that of uncoated PEEK samples, which showed a coefficient of friction of ～0.3. |
