In order to explore the dynamic characteristics of droplet impact on micro textured superhydrophobic surfaces under low Weber conditions,the triangular texture micro nano weave is prepared on the surface of Ti 6Al 4V specimens for aerospace applications using laser micro weave technology with nanosecond lasers at different scanning speeds,and the dynamical behavior of water droplets impacting on flat and oblique surfaces is investigated with the help of a high speed camera experimental platform.The experimental results show that the higher the height of the water droplet impact flat surface,the less air enters into the lamella,which increases the maximum spreading coefficient.Compared with the flat surface,more air enters into the lamella when sliding on the slanting surface of the same height and the maximum spreading coefficient is the smallest.Among them,at a scanning speed of 100mm/s,the proportion of the surface bump reaches 64.611%,the surface nanoparticles are the largest,the micron particles are the most,and the static and dynamic contact characteristics of the surface are optimal.The synergistic effects of surface structure and surface energy jointly affect the state of water droplets bouncing off the surface.This experiment can provide a reference for the preparation of superhydrophobic and active anti icing surfaces in the aerospace field.
