The object of the research are ozone recovery mechanisms that allow scientifically predict corrosion resistance of structural metals. The purpose of the work - to investigate the process of materials corrosion in the presence of ozone on the basis of scientific bases and to give reasonable recommendations for the selection of structural features in systems involving ozone. In the process, a comprehensive experimental and theoretical study of ozone influence patterns on corrosion processes, the development of theoretical ideas about ozone-oxygen depolarization, the development of principles for predicting corrosion behavior and the selection of structural metals for ozone synthesis. As a result of research, ideas about ozone-oxygen depolarization and mechanisms for ozone recovery have been developed, which allow science to predict corrosion resistance of structural metals. For the first time on an example of Ni performed ab initio quantum-chemical calculations of the electronic structure of individual cluster surface of the metal, which have structural "defects" of lattice. The practical significance of the work is that the models of the initial stages of formation of oxide films during ozone-oxygen depolarization were proposed, which allow to predict the behavior of structural materials. Developed and implemented experimental and analytical method of determining the concentration of ozone in aqueous acids.
