In this study, the Nd∶YAG pulsed laser is used for performing micro-modeling on the surface of a high-silicon aluminum alloy cylinder liner and the influence of typical laser parameters on its micro-dimple geometry is studied. When the energy density increases, the diameters of the micro-dimples initially increase and subsequently remain constant (the maximum diameter is 100 μm); the laser energy density only slightly affects the depths of the dimples. The diameters and depths of the dimples initially increase and then decrease with the increasing number of pulses. The maximum diameter and depth of the dimple are 140 μm after 20 pulses. Further, the ablation threshold φ_th of the high-silicon aluminum alloy is 2.08 J/cm ² in case of one pulse, which decrease with an increase in the number of pulses owing to energy accumulation. In addition, the effect of microtextures on the wear reduction of the cylinder liner surface can be observed at a fixed depth and diameter of the micropits, and the samples with area fractions of 10% and 20% exhibite better wear properties than those with an area fraction of 5%.
