Abstract

Recently, the application of femtosecond laser ablation of nickel to prepare super-hydrophobic structures in marine anti-corrosion has become more and more mature, but the processing efficiency is slow, which limits its large-scale application. In this study, a method for improving the efficiency of ablating nickel through multiple scaning of femtosecond lasers single pulse is proposed. The experimental results show that when the total processing time is the same, the higher scanning speed and more scanning times will promote the increase of the groove depth formed by the ablated nickel compared with the low scanning speed. This phenomenon has been verified under three different laser fluences. Compared with 25 um/s, the ablation efficiency is increased by 42.6%, 48.2% and 55.4% when scaning speed is 200 um/s, respectively. The difference in ablation efficiency in the experiment is related to the fact that femtosecond laser ablation of nickel will change the physical and chemical properties of the bottom of the material.
