To ensure the required performance characteristics of metalware, various types of 3D and surface process treatment methods are used in the industry. In order to ensure the required durability of parts under a high-load operation, various protective coatings are widely used in practice. However, most of these have significant disadvantages, manifested, for example, in the complexity of the technological process, high porosity of the coating, low mechanical properties, which restrict the scope of their application. The paper presents the results of the analysis of existing production methods for applying of metal coatings. Their advantages, disadvantages and influence on the performance characteristics of metal structures are provided herein. The most popular way to protect ferrous metals against atmospheric, soil and water corrosion is galvanizing. At the same time, regardless of their effect on the endurance of smooth samples, the endurance limit of the samples with stress concentrators increases. The corrosion resistance of steels is increased by many types of diffusion saturation (chrome plating, galvanizing, etc.); however, there are no data on the optimal values of the coating thickness. Limited theoretical and experimental data make it difficult to predict the physical and mechanical characteristics of coated metals and alloys. In addition, as a rule, there is no systematic comparative analysis of the negative impact of metal coating technologies on the environment quality in the literature.
