Experimental evaluation reveals how microindentation affects lubrication efficiency in steel surfaces, suggesting optimal texture for reduced friction.
Lubricated Friction The cover illustrates the microscopic result of the micro indentations analyzed in the study. The images highlight how small variations in dimple size and density influence the way the lubricant distributes across the surface. The work shows that only fine scale textures effectively enhance lubrication, whereas larger dimples induce flow instabilities that increase friction.
