Abstract
Aim. Modeling the properties of hydrophobic and ice-repellent coatings.
Methodology. The methods used are based on the use of known generally accepted laws of mechanics, electrodynamics and thermodynamics. The equations were solved numerically using proprietary computer programs, and the graphs were constructed using known graph plotting programs.
Results. The conditions for superhydrophobicity were formulated. Analytical studies of the features of applying relief to a metal surface using laser ablation were conducted. A method for controlling the spatial period of relief by changing the parameters of the laser system was proposed. Based on published experimental data on laser ablation, the possibility of satisfying the conditions of superhydrophobicity of modified aluminum, titanium and steel surfaces was shown.
Research implications lies in development of methods for modeling hydrophobic and ice-phobic properties, as well as in modeling and optimizing the processes of their creation. The use of such coatings allows for a significant reduction in the intensity of icing of aircraft, the drag of bodies in liquid, and the drag of aircraft in conditions of heavy precipitation.
