The protective coating deposited by ion-plasma sputtering have a very vivid aesthetic and decorative properties that make them attractive for solving design problems, and also enhance the operating characteristics of the products (increases strength, hardness, durability). The main stages of obtaining protective and decorative coatings by electric arc method, namely condensation by ion bombardment (CIB), are considered. The properties of the cathode substance, and hence the compounds formed by

... hese substances, depend on their position in the periodic table. The dependence of the coating properties and features of the electronic structure of the material from which the cathode is made is analyzed. The effect of ion-plasma treatment of the surface of glazed ceramic tiles on their properties is studied. The distinctive features of the structure of the glaze layer of domestic and foreign ceramic tiles are revealed.
