Аннотация:The present work demonstrates the possibility of fabrication of superhydrophobic (SHP) coatings on the surface of technically pure magnesium using laser texturing followed by modification in organic acid solutions. A comparison of the three methods of preliminary preparation showed that, by means of a laser marker, it was possible to create a greater surface roughness than at sandpapering or etching. In addition, such a surface would be uniform, in contrary to that after etching. Of the studied compounds, octadecylphosphonic acid (ODPA) is the best hydrophobizer. To attain the superhydrophobic properties of Mg90 by means of it, an ethanol solution of a lower concentration than stearic (SA) or oleic (OA) acids (1 and 10 mmol, respectively) is necessary. The results of corrosion tests have shown that the SHP coatings of ODPA provide longer-lasting protection than OA and SA films
