The work contains the results of theoretical and experimental studies of the processes occurring in metallic materials and various liquids under the action of power ultrasound. The obtained foundations and priorities developed at the world-class level have been implemented in certain industries to improve the operation life of products and structures, as well as product quality using ultrasonic cavitation technologies in the industry, medicine, and everyday life. To solve these tasks, a considerable number of new modifications of ultrasonic equipment for ultrasonic impact treatment (UIT) of the surface of machine-building products and welded constructions, ultrasonic welding of plastics, cavitation treatment for dispersion, disinfection, filtration, and extraction of liquids, and their stirring at the molecular level were created.
The underlying conceptual principles for increasing the resource of new and prolonged exploited products, welded structures and constructions by modifying their surface are developed based on of modern approaches to prolongation of the fatigue crack initiation stage and prevention of the crack development. The instrumental methods for establishing the effective technological parameters of UIT and for controlling the treatment quality are offered.
The introduction of ultrasonic technologies in many enterprises and companies determines the high scientific and technical level of work. UIT was implemented at PJSC "Kryukiv Carriage Works" in the manufacturing rout of the components and constructions of passenger carriage/ UIT is actively used following the regulatory documents of JSC "Ukrzaliznytsya" at repair and restoration works of the welded runways of the railway bridges to increase their operational resource.
The scale of the research, conducted over many years by the authors of the work, covers almost all cases of the use of powerful ultrasound in industry, and medicine, and promotes the development of "eco-friendly" technologies in all industries, therefore, the results of work are of national importance.
Some of the authors’ developments have no analogues or complied with the best foreign counterparts. The obtained results implemented at the mentioned and other enterprises of various industries of Ukraine gave a comparative economic benefit of 2000 million uah, and a direct one of 225.53 million uah.
Number of publications: 379, including 10 monographs, 2 regulatory documents 367 articles (58 - in foreign journals). Total number of the authors publications citations according to the SCOPUS database is 1122, h-index – 16; total number of links in the Google Scholar database is 2133, h-index – 22. Novelty and competitive ability of the technical solutions were protected by 76 patents. There were prepared 5 Doctoral and 15 Ph.D. dissertations.
