| description | ZrO<sub>2</sub> ceramics, known for their high strength and wear resistance, are ideal for artificial joints. This study enhanced the friction performance of these joints by fabricating textured structures (50 μm width and 20–25 μm depth) on the ceramic surface. Friction tests, conducted at 200 r/min for 30 min with a 5–20 N load and lubricant concentration of 15–60 mg/mL using PEEK balls, showed that textured joints outperformed untextured ones. The symmetrical triangular structure had the lowest coefficient of friction and the best hydrophilicity, with a 53.0% reduction in the coefficient of friction and a 57.4% reduction in the contact angle compared to the untextured structure. The textures effectively store the PEEK residue and facilitate the smooth movement of the worn ball. Concurrently, the textured structure stores some of the lubricant, which reduces the static pressure during fluid flow by 12.6%. Overall, the friction performance of ZrO<sub>2</sub> ceramic artificial joints was significantly improved by the textured structures. |
