摘要：

In this paper, ionic liquid (IL) diamond-like carbon (DLC)-based solid liquid lubricating coatings were used to conduct friction and wear experiments under a high-vacuum condition with alternating temperatures between -100 and 150 degrees C. The results showed that the friction coefficients at 100 and -100 degrees C were the lowest and the largest, respectively. Considering that the mobility, activity, spreadability, and self-repairing capacity of IL were significantly better at high temperatures compared with those at low temperatures, the DLC film surface slightly graphitized at a relatively high temperature. The disc wear rates were the lowest at room temperature and the highest at 150 degrees C because the surface graphitization of the DLC film and the large friction coefficient resulted in an increase in wear rate.
