Summary: The study found that under different sliding conditions, dimples defined by nanosecond laser exhibited the lowest steady-state coefficient of friction, while in Hank's solution, lines and crosshatching showed better frictional characteristics after running-in and the removal of bulges around the laser textures. In terms of wear resistance, low-density lines pattern and particularly dimples were the most promising in contact situations likely to occur during starved/dry-lubrication conditions.
