REQUIREMENTS FOR THE PARAMETERS OF MICROARC OXIDE COATINGS DEPENDING ON THEIR FIELD OF APPLICATION

Background. Due to the increased interest in the use of oxide coatings in various industries, including medicine and electronics, it is necessary to systematize the known requirements for the quality parameters and operational properties of microarc oxide coatings, depending on their field of application. The aim of the work is to establish the compliance of the quality parameters of microarc oxide coatings with the requirements depending on their field of application. Materials and methods. The requirements for the performance characteristics of high-strength protective coatings obtained by microarc oxidation are analyzed in the context of their application in aerospace engineering, mechanical engineering, and medical devices. Results. Based on the analysis of specific examples of existing applications of microarc oxide coatings, the requirementsfor their operational characteristics have been identified. Examples of multifunctional oxide coatings on aluminum and titanium are considered from the point of view of these requirements, and the expediency of their use in mechanical engineering, the aerospace industry, and medical devices is shown. Conclusions. The results obtained were used in the development of a digital twin of the process of obtaining microarc oxide coatings with specified properties.
