Abstract In this work, the effect of surface texture combined with conductive grease (CG) on the sliding friction characteristics of carbon brushes was studied. Mainly studied the influence of CG on the tribological properties of carbon brushes and the collection effect of surface texture on carbon powder. Studies have shown that a conductive lubricating film is formed on the surface of the carbon brush, and a large amount of carbon powder is detected in the surface texture holes of the carbon brush, indicating that surface texture can be used as a collector for carbon powder. In addition, the coefficient of friction (COF) of D172 carbon brush drilling and filling with CG is reduced by about 29%～56% and 47%～49%, respectively.

表面纹理和导电油脂填充对碳刷摩擦学性能和导电性的影响

摘要 在这项工作中，研究了表面纹理结合导电油脂（CG）对碳刷滑动摩擦特性的影响。主要研究CG对碳刷摩擦学性能的影响以及表面纹理对碳粉的收集效果。研究表明，在碳刷表面形成了一层导电润滑膜，在碳刷表面纹理孔中检测到大量碳粉，表明表面纹理可以作为碳粉的收集器. 此外，D172碳刷钻孔和填充CG的摩擦系数（COF）分别降低了约29%～56%和47%～49%。
