Investigation of functional properties of metal surfaces after laser treatment

This article presents the results of the study of the processes of formation of the metal surface, which has different hydrophysical properties and high chemical resistance to acidic media. The dependence of the contact angle of the surface (θ) on various parameters of laser processing material, the density of arrangement of the scanning vectors, the depth of the heated layer, the presence of oxide layer, etc. Determined optimum modes of laser processing, with which it is possible to obtain the greatest hydrophobicity, and maximum adhesion to the metal surface.
