Leidenfrost temperature are experimentally investigated. The functional surfaces were
fabricated on a 304 stainless steel surface via femtosecond laser surface processing (FLSP).
The droplet lifetime experimental method was employed to determine the Leidenfrost
temperature for both machine-polished and textured surfaces. A precision dropper was used
to control the droplet size to 4.2 μL and surface temperatures were measured by means of …
