Resumo

The method of superhydrophobization of the epoxy enamel layer based on the use of pulsed laser treatment and chemisorption of fluorinated silane on the textured enamel surface is proposed. It is shown that flexible control of laser irradiation parameters makes it possible to texture the enamel surface without overheating and subsequent destruction. Experimental studies have shown that the proposed superhydrophobic treatment can significantly improve the protective properties of enamel and impart it new functional properties, such as water-repellent properties with extreme contact and roll-off angles, increased resistance to both abrasive loads and surface stresses arising in the three-phase contact zone during water crystallization and ice melting.
