Impregnated graphite has attracted considerable attention and has been widely used as an ideal friction material in many fields. However, the influence of the friction temperature on its tribological properties has not been clearly studied; furthermore, the evolution mechanism of transferred tribofilm is unknown. In this study, the tribological properties of impregnated graphite were investigated at different friction temperatures, and the evolution of the carbon-based tribofilm was also determined. The results revealed that the tribological properties significantly improved with an increase in friction temperature. The friction coefficient and wear depth of impregnated graphite reduced by 68% and 75%, respectively, at a high temperature of 160 °C compared with those of non-impregnated graphite. The significant properties of the impregnated graphite can be attributed to a transferred carbon-based tribofilm with an ordered structure induced by the friction temperature, which uniformly and stably adsorbs on friction interfaces. This study provides an important basis for designing graphite-based friction materials with improved properties suited for industrial applications.

浸渍石墨引起了广泛的关注，并已在许多领域中广泛用作理想的摩擦材料。但是，摩擦温度对其摩擦学性能的影响尚未得到明确研究。此外，转移的摩擦膜的演化机理尚不清楚。在这项研究中，研究了浸渍石墨在不同摩擦温度下的摩擦学性能，并确定了碳基摩擦膜的演变。结果表明，摩擦性能随着摩擦温度的升高而显着改善。与未浸渍的石墨相比，在160°C的高温下，浸渍的石墨的摩擦系数和磨损深度分别降低了68％和75％。浸渍石墨的显着性能可以归因于由摩擦温度引起的具有有序结构的转移的碳基摩擦膜，该摩擦膜均匀且稳定地吸附在摩擦界面上。该研究为设计具有改进性能的石墨基摩擦材料提供了重要基础，该材料适合工业应用。
