Improvement of the Technological Process of Obtaining Protective and Decorative Coatings

Abstract

To improve the performance properties of metal surfaces, not only composite, but also multilayer electrochemical coatings based on various metals and alloys can be used. According to economic calculations, it is found that it is more profitable to use the Sn-Ni alloy as a protective and decorative coating than the Сu-Ni-Cr multilayer coating
