“…As a rule, the metallic materials used in mechanical engineering should provide a combination of strength, ductility and cyclic durability, taking into account the impact of aggressive environments on them, since the operational reliability of products made from steel structures is determined by the resistance of their materials to static, cyclic and corrosive destruction [5][6][7][8]. To ensure the required consumer properties of metallic products, various types of surface process treatment methods, both 3D and surface, are used in the industry [9][10][11]. In practice, a widely used method of ensuring the required durability of parts under a high-load operation is a protective coating [10][11][12].…”

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.

“…The effective method of this modification and as a consequence, fatigue life increase is the processing of material surface by high intensity electron beam of submillisecond effect duration, allowing to change the surface layer structure tens of micrometres thick into a multimodal structure-phase state and essentially without changing the structure-phase state of the alloy basic volume. [4][5][6][7][8][9][10][11][12] Alloys of aluminium with silicon having high specific mechanical properties are brittle and are difficultly deformed materials. The structure and phase composition of aluminium alloys are widely investigated.…”

Processing of Al–19·4Si alloy by high intensive electron beam has been carried out, and multiple increase in fatigue life of the material has been revealed. Investigations of structure and surface modified layer destruction of Al–19·4Si alloy subjected to high cycle fatigue tests to fracture have been carried out by methods of scanning electron microscopy. The factors responsible for the increase in fatigue life of Al–19·4Si alloy have been revealed and analysed.
