Abstract
The paper presents the results of experimental studies to determine the effect of surface treatment of galvanized steel using laser equipment on wettability properties and corrosion resistance. It is shown that laser texturing of the roughness on the zinc layer contributes to the achievement of the hydrophobic state. It is noted that during ablation and discontinuity of the zinc layer on the steel surface, the hydrophobic state is achieved only due to the formation of molecular layers of the surfactant. An increase in the corrosion resistance of galvanized steel was achieved by activating the zinc layer due to laser texturing of the surface at a radiation density of 20 and 35 J/cm2. With ablation and discontinuity of the zinc layer on the steel surface, the corrosion resistance is significantly reduced.
