Experimental Study on Anti-Friction Property of Groove Textured Surface with Different Direction Angles

Article Preview

Abstract:

To investigate the influence of different direction angles on groove textured surface, tribology experiments for smooth surface and groove textured surface with angles of 0°, 30°, 45°, 60°, 90° were carried on under various loads and velocities. The results show that, the friction coefficient decreases first and then increases with the increase of groove direction angle. And the optimal anti-friction effect could be obtained when the groove textured surface with angle of 60°, because of its superior combined effect of resistance force and liquid squeeze force, which are introduced by the groove. The findings could provide a theoretical guide for the design and application of groove textured surface.
