Hypothesis Contact line movement over laser-textured metal alloy surfaces depends on the texture, droplet state, inversion of wettability, and liquid flow rate. Experiments Ordered and anisotropic textures were created by a nanosecond pulse laser on aluminum-magnesium alloy surfaces. Microrelief was studied on a profilometer and scanning electron microscope. Changes in wetting properties and the characteristics of spreading were obtained. To implement wetting cycles, liquid was dispensed with a syringe pump using the bottom-up method.Findings The results provide new, in-depth knowledge to understand the mechanisms of the contact line movement on laser-textured metal surfaces. We have shown that by creating a texture with given parameters (ordered or anisotropic), it is possible to predict a change in wettability from superhydrophilic to hydrophobic, as well as a droplet state. In this paper, we have demonstrated that the contact angle hysteresis determines not only the deviation of the contact angle from equilibrium, but also the adhesion force between the droplet and the surface, a droplet state (Wenzel or Cassie-Baxter), and the wetting anisotropy of local areas on laser-textured alloy. We have recorded two states of the droplet on formed textures: the Wenzel with air cushions on anisotropic and the Wenzel with complete filling of cavities with water on ordered textures.
