Thermal Ice Melting Performance of Femtosecond Laser Metal Micro-Nano-Structured Surface

Abstract

AbstractImproving thermal ice melting efficiency is very important in the practical application of anti-icing surfaces. This work investigated the thermal ice melting performance of micro-nano-structured surfaces fabricated by femtosecond laser. To the best of our knowledge, we found that the micro-nano-structured surfaces significantly improve the ice melting time for the first time. The shortest melting time was on the porous micro-nano-structured surface, about one third of the original surface. Moreover, it was proven that the accelerated ice melting surface had good durability. The research in this paper showed that the micro-nano-structured surfaces are very suitable for the surface that needs to be heated to melt ice, providing essential guidance for the design of the anti-icing surface.
