摘 要:为了解决国产钢领使用寿命短、锭速低,制约纺纱效率提高的问题,以DLC镀膜钢领为对象,重点对纺织纤维粘着物粘着在钢领表面引起的钢领轨道破坏,以及相关的粘着磨损和疲劳磨损破坏机理进行了分析。针对其失效情况,探讨将单一DLC镀膜改进为Ti-DLC镀膜,即采用非平衡闭合磁控溅射技术和钛(Ti)掺杂多层复合镀膜技术,在基体温度低于100℃的条件下,在钢领表面制备Ti-DLC复合膜,并研究不同钛含量对膜的结构、摩擦磨损性能的影响。改进后的Ti-DLC膜比DLC膜具有更高沉积率、更高粘附力、更高的硬度和耐磨性、低摩擦因数和低磨损率等性能,改善了钢领表面膜的摩擦磨损性能,克服了常规DLC镀膜的缺点,从而保证其抗粘着性、抗疲劳性更好。In order to solve the problems with the domestic rings such as short service life, low spindle speed,restricting the spinning production, sampling the filmed ring DLC. Analysis is given to the mechanism of the path spoilage of the ring due to the adhesiveness of the fiber on the ring and the adhesive wear and tear and the fatigue abrasion. Considering the failure, approach is done into the possibility of filming the ring with the integration of the non-offset close magnetic controlled splashing process and the Ti-inter- mingled multiplied filming process, namely, Ti-DLC filming process instead of DLC filming process. The ring is Ti-DLC filmed when the tempreture of the ring body is under 100 ℃. The Analysis is done to the imapct of the Ti content of the film on the structure of the film and the performance of the wear and tear. It provs that the Ti-DLC filming process is of more sediment, high adhesiveness,and more wear-resistance, low friction factor and low spoilage. The Ti-DLC filming process upgrades the performance of the wear-re- sistance, overcoming the disadvantage of the conventional DLC filming process, resulting in better adhesiveresistance and fatigue-resistance.
