摘　　要：为探究不同工况条件下碳纤维增强聚醚醚酮(C-PEEK)复合材料制件的摩擦与磨损性能,通过熔融沉积3D打印进行高精度C-PEEK复合材料制件,采用对置往复摩擦磨损试验机对不同配对副、外加载荷、滑动速度、接触时长和温度条件下的C-PEEK样件进行分析。结果表明,随着接触时长、滑动速度以及外加载荷的增加,C-PEEK材料的磨损量虽然会有所提升,但摩擦系数总体均维持在0.3及以下,具有较好的耐磨性。在滑动速度为15mm/s、载荷为30MPa、试验时长为1h时,随温度的升高,C-PEEK材料磨损量也会增大,但摩擦系数逐渐减小。此外,温度为200℃时GCr15钢球+C-PEEK摩擦副间的摩擦系数可低至0.15,展示了C-PEEK复合材料良好的摩擦磨损性能。To explore the friction and wear properties of carbon fiber-reinforced polyetheretherketone(C-PEEK)composite specimens under different operating conditions,high-precision C-PEEK composite specimens were fabricated using fused deposition modeling(FDM)3D printing.The specimens were then subjected to reciprocating friction and wear tests using a pin-on-disc tribometer under various pairing counterparts,external loads,sliding velocities,contact durations,and temperature conditions.The results showed that,although the wear volume of C-PEEK material increased with increasing contact duration,sliding velocity,and external load,the friction coefficient remained generally below 0.3,indicating good wear resistance.Under the conditions of a sliding velocity of 15 mm/s,a load of 30 MPa,and a test duration of 1 h,the wear volume of C-PEEK material increased with temperature elevation,while the friction coefficient gradually decreased.Additionally,at a temperature of 200℃,the friction coefficient between GCr15 steel ball and C-PEEK friction pair could be as low as 0.15,demonstrating the excellent friction and wear properties of C-PEEK composite material.
