In order to explore the droplet impact characteristics of laser etched titanium alloy micro textured superhydrophobic surfaces at different scanning speeds,one step laser etching is performed on the surface of industrial material TC4 (Ti 6Al 4V).The surface morphology is observed by scanning electron microscope and confocal electron microscope.The wettability of the surface is measured by contact angle measuring instrument,and the droplet impact process is captured by a high speed camera experimental platform.The results show that the hydrophobic performance of the surface is the best when the scanning speed is 200mm·s -1,under the combined influence of surface microstructure and surface chemical properties.The surface with good hydrophobicity has a larger maximum spreading coefficient of droplets due to low viscous dissipation.
