Optimization of laser surface texturing for improving the tribological properties of anti-friction plates

Effective reduction of friction and wear is an important issue that must be addressed in many engineering equipment applications. In this study, laser texturing technology was used to texture an SA508 Gr.3 Cl.2 anti-friction plate with different shapes (circle, semicircle, square, etc.). Based on the simulation results of the pressure distribution, the optimized shape that ensures uniform normal stress distribution was determined. Subsequently, according to the tribological experiments, the influences of different texturing shapes and texture densities on the frictional performance were studied. The results reveal the influences of factors such as shape and density on anti-friction and stick-slip suppression. Therefore, this study provides a new methodological basis for anti-friction and stick-slip suppression in nuclear power equipment under high-temperature, low-speed, and heavy-load conditions.
