| 摘 要： | 采用纳米复合非平衡等离子体镀膜方法制作了应用于月球车活动关节的新型TiN-MoS2/Ti复合润滑薄膜,通过SEM、XPS等对复合薄膜的微观结构和成分进行了分析,并进行了耐磨和抗潮湿性能试验。研究结果显示,与传统多层膜结构相比,TiN-MoS2/Ti新型复合膜的钻孔数从278个提高到356个;潮湿储存10d后,其耐磨性能与多层膜相比,提高了2.5倍。因此,通过优化制备工艺及加入Ti添加剂等方法可以有效提高月球车活动关节处润滑薄膜的耐磨和抗潮性能。 |

| Abstract: | A new TiN-MoS_2/Ti composite coating was successfully prepared using the nano-compound unbalanced plasma-plating technique for the flexible knuckle of moon exploration robots. The microstructures of the as-prepared coatings were analyzed by SEM with the compositions analyzed by X-ray photoelectron spectroscopy. Dry drilling and reciprocating wear experiments were used to investigate the tribological and wear-resistive properties in humid air. The results show that the number of drilling holes of the TiN-MoS_2/Ti coatings is increased from 278 to 356 compared to a traditional multilayer structure. When stored in humid air for 10 days, the wear lifetime of this new MoS_2-based coating is improved 2.5 fold compared to a multilayer coating. The results confirm that the tribological performance and wear resistive properties of these MoS_2-based coatings are markedly enhanced by optimizing the processing parameters and introducing Ti additives during the deposition of the MoS_2-based coatings. |
