Application of Ultra High Speed Laser Cladding Technology for Functional Coatings Deposition

The technology of high speed laser deposition is a development of the method of applying functional coatings using a laser beam. It is characterized by high surfacing speeds, allowing high cooling rates, little mixing with the substrate, which leads to a high purity of the padding material and an increase in the properties of the applied layer compared to conventional laser welding. This paper presents a description of the technology of high speed laser deposition in an application for the aviation industry. The prepared stand for the implementation of the process and its verification on the aircraft landing gear component, modified as part of the AMpHOra project, has been presented. The project was carried out as part of the PZL Mielec consortium and with the scientific partner of the Wrocław University of Technology. The results presented in the article show that the coatings obtained by this technology can be competitive with hard chromium electrolytic coatings.
