Anti-friction mechanism of sinusoidal texture with various intervals: The synergistic effect of dynamic pressure and tribofilm

Reasonable texture intervals can effectively generate a local dynamic pressure effect and promote the tribofilm formation. A friction experiment combined with simulation analysis is employed to investigate the effect mechanism of sinusoidal texture intervals on surface friction properties. The syner...

Description
Summary:Reasonable texture intervals can effectively generate a local dynamic pressure effect and promote the tribofilm formation. A friction experiment combined with simulation analysis is employed to investigate the effect mechanism of sinusoidal texture intervals on surface friction properties. The synergistic antifriction mechanism between the hydrodynamic pressure effect of texture and the tribofilm is discussed. The results display that synergistic texture lubrication has a beneficial effect on improving tribological properties. The surface with a textured area density of 25% displays the optimal tribological properties. Moreover, friction reduction mechanism under different working conditions is discussed. Higher sliding speed is beneficial to anti-friction property by promoting dynamic pressure lubrication, while larger load mainly facilitates the formation of surface friction film to reduce friction.
