In this work, a bio-inspired surface texture was developed to regulate lubricant migration and interfacial lubrication. Reciprocating friction tests in horizontal and vertical orientations were conducted to examine how thermal gradients and gravity influence the lubrication behavior of textured surfaces. Results demonstrated that surface texturing can effectively reduce friction and control lubricant loss under different directional forces. In simulated point-to-plane contact of the rotating pair tests under low-speed, light-load rotation, the textures enhanced resistance to centrifugal effects and improved lubrication stability. These findings confirm the potential of biomimetic surface designs for improving point-to-surface lubrication in complex operating conditions, with promising applications in aerospace bearings and precision motion systems.
