The staff of the Research Laboratory "Laser and Additive Technologies" of the Institute of Metallurgy and Metallurgy of the St. Petersburg Polytechnic University completed a key stage of R&D within the framework of the delivery of a technological complex for laser powder cladding for the LLC "UK "KER-Holding".
Engineers from the Research Laboratory "LiAT" of the Institute of Metallurgy and Metallurgy of the St. Petersburg Polytechnic University completed the practical part of the project aimed at transferring laser surfacing technologies for the restoration of gas turbine engine components, and conducted acceptance tests of the previously delivered laser powder surfacing technological complex.
The work was carried out as part of the second stage of R & D. The main objective was to implement and test laser cladding modes on two types of parts and control samples, including components made of heat-resistant nickel superalloys. The focus of the project was the restoration of the SGT-300 first-stage nozzle blades and the first-stage working blades of the Taurus 60 gas turbine engine.
All stages were accompanied by a full technological cycle: coordination of sample geometry, fluorescent testing for cracks, development of technological instructions, design and manufacture of equipment.
Mikhail Kuznetsov, Head of the Research Laboratory "LiAT" of the SPbPU Institute of Metallurgy and Metallurgy, noted: The laboratory staff successfully carried out acceptance tests of the laser cladding complex and demonstrated the applicability of the developed technologies taking into account the specifics of real production conditions. At the next stage, it is planned to equip the complex with a sealed chamber.
Long-term cooperation with UK KER-Holding LLC is one of the examples of how scientific developments of the Scientific Research Laboratory LiAT of IMMiT SPbPU find real application in industry. This is an important step towards the introduction of import-substituting technologies in the field of aviation and power engineering.
