Laser Surface Texturing for Ground Surface: Frictional Effect of Plateau Roughness and Surface Textures under Oil Lubrication

Blog Article

Laser surface texturing has proven beneficial in improving tribological performance in different lubrication regimes.However, the interaction between plateau roughness and surface texture remains to be further investigated, even though rough surfaces are common in engineering read more applications.In the present study, we investigated the frictional influence of surface texturing of ground surfaces under different lubrication conditions.Channel textures with different depths and area ratios were fabricated on ground surfaces, and their friction was tested in reciprocating tests.

The experimental findings indicate that the textures caused increased friction for ground surfaces under boundary or mixed lubrication when the interface is well lubricated.Nevertheless, when opheliasmuse.com the oil supply was limited, an up to 40% friction reduction was observed under test conditions.
