The aeronautical industry investigates new repair techniques

Currently the aeronautical industry considers the need to improve the repair techniques of the metal components within the structure of the airplanes, both in the engine parts and in some elemental structures. In this context, researchers from the Rey Juan Carlos University (URJC) search for new solutions and new techniques through its participation in the European project Cold Spray Radical Solutions for Aeronautic Improved Repairs (CORSAIR). The goal is to overcome the current technological limitations and achieve more efficient systems of maintenance and repair of aeronautical components to extend the life of aircraft. At the moment, the team has developed new alloys of aluminium trioxide with nickel, (Ni-Al2O3), in this case more focused on the power generation industry. The details have been published in the Journal of Thermal Spray technology. This study and the CORSAIR consortium is based on the processes of cold spray, a relatively new technique – the first patent dates from the 90s – that presents advantages for depositing light alloys, mainly with a titanium, aluminium and magnesium base. According to its promoters, its development is sufficiently mature to explore its industrial use. The department of Mechanic Technology of the Rey Juan Carlos University forms part of this European multidisciplinary consortium and composed of different groups of investigation from European universities (Milan Polytechnic and the National Aerospace University Kharkiv) – and different technological centres (Veneto Nanotech and TWI). The application in the aeronautical industry has contributed to the companies of the sector also being involved, such as the Spanish companies Iberia Mantenimiento and Airbus Militar and other European companies (General Electric Avio, EADS Deutschland GMBH, METALogic, Impact Innovations, LPW Technology y EASN-TIS).
