Tribological Properties and Oil Flow Observation of Porous Sintered Metal with Dimple Texturing by Block-on-Disk Friction Tester

Presence of micrometer-scale textures on a surface can modify the friction properties of that surface. In this study, we investigated the fundamental tribological properties of Cu-Sn porous sintered metal with the rounded rectangle dimple texturing under hydrodynamic lubrications. The results of blo...
