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 po tential of biomimetic surface designs for improving point-to-plane lubrication in complex operating conditions,  with promising applications in aerospace bearings and precision motion systems.
