Registration Date 12-01-2023 Organization National Technical University of Ukraine "Igor Sikorsky Kyiv Polytechnic Institute" popup.description2 During the implementation of stage No. 1 (final) of the project, experiments of severe surface plastic deformation by ultrasonic and shot peening of steels after preliminary laser surface hardening were carried out. Laser heat treatment of AISI 1045/30HGSA and AISI D2 steels was performed according to the statistical design of the experiment using a modern high-power robotic laser system at the New Technologies Research Centre of the University of West Bohemia as part of a foreign business trip (November-December 2021, Pilsen, Czech Republic). Optimization of the technological regimes of laser surface hardening with a fiber and disk laser was performed. The study of the influence of laser surface hardening with overlap of tracks on the quality parameters of the surface layer was carried out. The proposed combined processing methods lead to increased corrosion resistance, ensuring surface integrity and durability of steel products. Based on the conducted theoretical and experimental studies, practical recommendations were developed for the implementation of a combined method of laser thermal-deformation hardening and finishing of steel products to increase the strength and wear resistance of steel products, including components and aggregates of automobile and armored vehicles.
