“…Dan et al 33 and Kashyap and Ramkumar 34 studied the effect of texture area ratio on the effect of wear reduction and drag reduction and found that different texture area ratios have different effects on the tribological properties of the friction pair. He et al 35 comprehensively compared the stress and temperature variations of three micro-texture shapes and concluded that the circular pit micro-texture was the most effective in reducing friction. Zhang et al 36 textured the surface of 42CrMo material, studied the effect of different texture area ratios on the tribological properties of the material surface, and found that the existence of texture effectively reduced the friction and wear of samples under grease lubrication conditions.…”

To solve the problem of premature failure of the rubber stator of the screw pump due to wear, reduce the frictional resistance torque of the screw pump to solve the problem of difficulty in starting after the shutdown of the screw pump production system in Daqing Oilfield. The effects of micron dot texture and lubricating medium on the tribological properties of 42CrMo metal and acrylonitrile–butadiene rubber mating surfaces were studied by theoretical analysis and tribological tests. The friction coefficient, wear amount, and rubber wear morphology were used as the measurement indexes of drag reduction, wear resistance, and wear degree, respectively. The results showed that the best combination of texture area ratio and the lubricating medium was 10% silicone grease, the friction coefficient and wear amount were reduced by 11% and 10.7%, respectively, compared with untextured, and the main order of chip storage and oil supply effect was 10% > 5% > 15%.

“…The application of consecutive laser pulses with sequential laser beam movement facilitates the creation of regular laser-formed surface structures, from simple periodical dimples or segments up to polygonal or hierarchical structures [ 1 , 2 , 3 , 4 ]. Such a process of periodical objects laser formation is named laser surface texturing (LST), and it has a wide range of applications: in tribology, material engineering, wettability, brazing, medicine, optics and other areas [ 5 , 6 , 7 , 8 ]. The development of laser surface scanning techniques is needed for increasing the processing rate of LST.…”

Laser surface texturing (LST) is one of the most promising technologies for controllable surface structuring and the acquisition of specific physical surface properties needed in functional surfaces. The quality and processing rate of the laser surface texturing strongly depend on the correct choice of a scanning strategy. In this paper, a comparative review of the classical and recently developed scanning strategies of laser surface texturing is presented. The main attention is paid to maximal processing rate, precision and existing physical limitations. Possible ways of further development of the laser scanning strategies are proposed.

In order to improve the lubrication performance of the friction pair, the effect of composite micro-texture on the lubrication performance of the tilting pad thrust bearing is studied. Based on the structural model of tilting pad thrust bearing considering composite micro-texture, the lubrication characteristics of thrust bearing with composite micro-texture parameters and tilting pad parameters are analyzed. At the same time, the theoretical model of tilting pad composite micro-texture bearing considering roughness and turbulence effect is established, and the performance of thrust bearing considering roughness and turbulence effect is studied. The results show that the performance of composite micro-textured bearings is better than that of single micro-textured bearings, the performance of tilting pad bearings is better than that of parallel pad bearings, and the performance of circular composite fish-shaped micro-textured tilting pad bearings is the best. The optimal bearing fulcrum position is near the inner diameter, and the optimal fulcrum circumferential inclination angle is about 27.5°. Considering the roughness and turbulence effect, the maximum pressure and bearing capacity of the bearing improves, and the friction coefficient significantly reduces.
