In order to improve the anti-wear performance of textile traveler ring in the high-speed conditions,diamondlike carbon (DLC) films were prepared on the traveler ring surface by using the direct-current plasma chemical vapor deposition method. The surface morphology of coating and its hardness were investigated by scanning probe microscope and microhardness tester. It is found that the diameter of the DLC particle is approximately of 100 nm taking on island morphology, the hardness of the thin DLC films at micro-level is probably derived of 18 GPa based on a simple mathematical model. The tribology property of DLC films at the velocities from 100 r/ min to 600 r/ min,the load from 20 N to 100 N was investigated by using ball-on-disk tribo-tester. It is found that with low load and high velocity,the DLC coatings have the best anti-wear features,which matches well with the actual working conditions of traveler ring in textile fabrication process. The wear mechanism of DLC films was addressed by Fourier Infrared Spectroscopy. The releasing hydrogen elements and shear stress in the wear process dominate the transition of graphite SP3 / SP2.
