An Experimental Study on the Effect of Lubricant Volume and Surface Texture on the Tribological Performance of Surfaces in Point Contact

Reduction of friction coefficient is always of great importance in various mechanical systems. In this research, the effect of surface texturing and the lubricant volume on the friction coefficient is investigated. The experiments are conducted using a pin on disk test rig and a mechanical setup is used to texturize the surface of the disks. The results show that Stribeck curve can be obtained in the textured case. It is also observed that surface texture reduces the friction coefficient but this reduction is more pronounced under heavy loads. In the case when very low amount of lubricant is provided, an increase in the applied load results in an increase in the lift-off speed.
