In today's environment, the production of competitive mechanical engineering products requires technologies that ensure high quality products and improve their performance. In particular, combined thermomechanical hardening using laser radiation and surface treatment is an effective technological method of increasing the wear resistance of parts.

Oleksandr Danyleiko, a graduate of the Department of Laser Engineering and Physical and Technical Technologies of the E.O. Paton Institute of IMZ, devotes his research to metal processing using special technologies. In 2016, he received a master's degree in specialty “Metal processing by special technologies” from Igor Sikorsky Kyiv Polytechnic Institute, and in 2024 he received a doctorate in philosophy, defending his dissertation on “Improving the performance properties of steel products by combined laser thermomechanical surface treatment” in specialty 131 “Applied Mechanics”.
“The Department of Laser Engineering and Physical and Technical Technologies has always been for me a place where science and practice merge into a single whole,” says the scientist, ”It is thanks to the professionalism and mentoring of the leading scientists of the department that I managed to build my scientific and pedagogical career. I would like to express my sincere gratitude to all the staff of the Department of Laser Engineering and Physical and Technical Technologies, who have always supported, mentored and helped me, and above all to the head of the department, Oleksii Dmytrovych Kagliak, my scientific mentors, Vitalii Vasyliovych Dzhemelinskyi, Leonid Fedorovych Holovko, and Dmytro Anatoliiovych Lesyk.”
The young scientist's research interests include the study of physical and mechanical properties of materials and the development of new combined and hybrid methods to improve the performance of parts operating in difficult production conditions. The main results of his research are highlighted in 62 scientific papers published in leading Ukrainian and international journals. Among them are 5 articles indexed in the international scientometric database Scopus, 15 scientific papers in professional journals of Ukraine (category B), and 5 articles published in foreign journals. He has also prepared one chapter in a collective monograph, received 11 patents and has 25 papers of an approbation nature.
Studying and working at Igor Sikorsky Kyiv Polytechnic Institute allowed the researcher not only to realize his ideas, but also to collaborate with colleagues from other higher education institutions and research institutions. In particular, during his studies at the university, he completed an industrial internship at Otto von Guericke University (Germany) and a language internship at the University of Passau (Germany). Currently, he is fruitfully cooperating with the research department of the E.O. Paton Institute of Electric Welding of the National Academy of Sciences of Ukraine, headed by Artemiy Bernatsky.
At the end of last year, Oleksandr Danyleiko, an assistant at the Department of Laser Engineering and Physical and Technical Technologies, was awarded a scholarship from the Cabinet of Ministers of Ukraine for young scientists. “I feel a great responsibility for the further development of my research, as well as gratitude and respect for our defenders who provide the opportunity to work, including for the needs of the Armed Forces,” the young scientist commented on the event.
Of course, the researcher's plans for the future are primarily related to science. “My work prospects include improving the methods of improving the operational properties of parts operating under difficult load conditions using highly concentrated energy sources,” he said.
At one time, the founding fathers of the KPI dreamed that engineers would not only have a good theoretical education, be able to operate machines and mechanisms, but also apply their knowledge to further improve engineering and technology - “have some passion for manual labor,” that is, be able to work with both their heads and hands. So in his free time, Oleksandr likes to assemble electrical circuits, practice with a soldering iron and other tools, create radio-controlled models for various purposes, and so on. And again, we mentally return to the instructions of the first rector of Igor Sikorsky Kyiv Polytechnic Institute, Viktor Kyrpychov: “To get new results, you need to constantly invent new things. To do this, you need to have a rich imagination.” Perhaps that is why O. Danyleiko prefers popular science books and technical literature. “I believe that research, modeling, and development of new devices and mechanisms are an important part of the engineering profession,” he said.
“Studying and working at the university taught me not to be afraid to set big goals, because science provides endless opportunities for development and self-improvement. And challenging tasks stimulate constant search,” the scholarship holder concludes.
