摘　　要：为研究分析不同表面处理工艺对钢丝圈纺纱性能的影响,进一步提高钢丝圈使用寿命,采用化学镀的方法向镀液中添加纳米碳化硅(SiC)和聚四氟乙烯(PTFE),制备Ni-P-SiC-PTFE化学复合镀层的钢丝圈。借助扫描电子显微镜、X射线能谱仪和环锭纺纱机等对钢丝圈及镀层的微观结构和性能进行表征。结果表明:相对于Ni-P化学镀钢丝圈,Ni-P-SiC-PTFE化学复合镀钢丝圈的镀层晶粒细化,厚度均匀,镀层与基体之间结合良好,镀层厚度增加1倍,镀层硬度提高24.5%;采用Ni-P-SiC-PTFE化学复合镀钢丝圈试纺后,纱线的细节、粗节和棉结分别降低40%、18.8%、10.3%,且钢丝圈挂花引起的断头率降低50%,纺纱性能优于Ni-P化学镀钢丝圈;Ni-P-SiC-PTFE化学复合镀钢丝圈上机后的磨损量减少了31.6%,耐磨性得到明显提升。In order to study and analyze the influence of different surface treatment processes on the performance of the traveler for yarn spinning and further improve the service life of the traveler,electroless plating was employed using a plating solution fabricated from nickel-phosphorus-nano-SiC-polytetrafluoroethylene(Ni-P-SiC-PTFE)to coat the traveller.The microstructure and performance of the traveler and the coating were characterized using scanning electron microscope,X-ray energy spectrometer and experimented on the ring spinning machine.The results show that compared to the Ni-P chemically coated traveler,the grains of Ni-P-SiC-PTFE chemical composite plated travellers are refined and uniform in thickness,and the coating is well attached to the substrate.It is found that the thickness of the coating is doubled,and the hardness of the coating is increased by 24.5%.After trial spinning using Ni-P-SiC-PTFE chemical composite plated travellers,yarn faults such as the yarn thin section,thick spots and neps are reduced by 40%,18.8%and 10.3%respectively,and the breakage rate caused by the hanging of the traveler is reduced by 50%,and the wear of the traveler is reduced by 31.6%,demonstrating superiority over the Ni-P electroless traveller.
