Abstract This study describes the effect of textured patterns on the lubrication performance in starved hydrodynamic lubrication. A friction test rig including an in-situ observation system is used with controlled lubricant quantity to create point contact between a convex glass lens and rotating steel disc. The in-situ observation system captures the meniscus pattern around the lubricated area as well as optical interferograms of the film thicknesses. Longitudinal or transverse grooves are created on discs, which improve lubricant supply into the lubricated area at high sliding conditions, compared to a flat disc. Mechanisms for improving the lubricant supply through textured patterns are discussed based on the in-situ observation results.

纹理表面对缺乏流体动力润滑的影响

摘要 本研究描述了纹理图案对缺乏流体动力润滑的润滑性能的影响。摩擦试验台包括原位观察系统，用于控制润滑剂量，以在凸面玻璃透镜和旋转钢盘之间产生点接触。原位观察系统捕获润滑区域周围的弯液面图案以及薄膜厚度的光学干涉图。与平盘相比，盘上形成纵向或横向凹槽，可在高滑动条件下改善润滑区域的润滑剂供应。基于原位观察结果讨论了通过纹理图案改善润滑剂供应的机制。
