Abstract The frictional vibration performances of textured surface coated with DLC(Diamond-like Carbon)film of dry gas seals ring were investigated. In the meantime, the mechanism of textured surface on interfacial tribological behavior was revealed under dry frictional condition. The acceleration and frictional force were measured by using universal friction and wear tester which type is MMW-1, and the surface topographies were measured by using SEM and ST400 three-dimensional non-contact surface topography instrument. Results show that the textured surface coated with DLC film can significantly improve the tribological behavior of dry gas seal. Textured surface with reasonable size parameters can capture debris and avoid strong impact between the friction pairs, which improves effectively the tribological behavior of interfaces.

带干气密封环的DLC薄膜微织构摩擦振动性能试验

摘要 研究了干气密封环织构化表面DLC（类金刚石碳）膜的摩擦振动性能。同时，揭示了干摩擦条件下纹理表面对界面摩擦学行为的影响机制。加速度和摩擦力采用MMW-1型万能摩擦磨损试验机进行测量，表面形貌采用扫描电镜和ST400型三维非接触式表面形貌仪进行测量。结果表明，涂​​有DLC薄膜的纹理表面可以显着改善干气密封的摩擦学行为。具有合理尺寸参数的纹理表面可以捕获碎屑并避免摩擦副之间的强烈冲击，有效改善界面的摩擦学行为。
