Study on the friction performance of textured surface on water hydraulic motor piston pair
To explore the effects of textured surfaces on the friction performance of a low-speed and high torque water hydraulic motor, a textured surface was designed on the friction pair. A transient simulation, a gap flow field simulation analysis, and a wear experiment were carried out according to the actual working conditions of the piston pair. The results showed that the connecting surface with ellipsoidal pits could improve the stability of the lubricating water film between the contact surfaces by improving the stress distribution on the surface of the piston pair and reduce abrasive wear by reducing the fall of matrix material. The experimental results showed that about 62.6% of the wear loss reduction could be reached using the ellipsoidal pit surface, and the wear loss mainly occurred in the edge of pits. Therefore, it is a reasonable design of textured pits surface to improve the surface friction performance of piston pair under working condition.

Abstract
To explore the effects of textured surfaces on the friction performance of a low-speed and high torque water hydraulic motor, a textured surface was designed on the friction pair. A transient simulation, a gap flow field simulation analysis, and a wear experiment were carried out according to the actual working conditions of the piston pair. The results showed that the connecting surface with ellipsoidal pits could improve the stability of the lubricating water film between the contact surfaces by improving the stress distribution on the surface of the piston pair and reduce abrasive wear by reducing the fall of matrix material. The experimental results showed that about 62.6% of the wear loss reduction could be reached using the ellipsoidal pit surface, and the wear loss mainly occurred in the edge of pits. Therefore, it is a reasonable design of textured pits surface to improve the surface friction performance of piston pair under working condition.
