Abstract

Laser polishing (LP) is a promising technology for improving surface quality. An important obstacle to the practical application of LP technology is the relatively narrow process window. Lots of previous studies have demonstrated that LP is often applied below the ablation threshold, causing a large gap in the process window for different materials, which depends on many parameters such as material absorption, phase transition temperature, dynamic viscosity and so on. Through comparative studies of several materials with different properties, including glass and alloy materials, we believe that the process window of LP can be appropriately sought from the perspective of molten pool dynamics. This investigation focuses on the evolution of molten pool flowing over time during the laser polishing process based on well-designed multi-physics numerical models and experiments.
