Canales S. Control of the coatings quality parameters and deposition efficiency of the gas-dynamic spraying on aviation parts

Object - the study of the cold spraying technology; objective - to study the characteristics of supersonic two-phase flows, their interaction with solid obstacles and their effect on the coatings formation for controlling physical-mechanical coatings characteristics on aviation parts; methods of study - the computational fluid dynamics, the finite difference and integration methods (Euler's method); theoretical and practical results - model, method, concept and recommendations that forms theoretical basics of coatings with predesigned properties forming by cold spraying; novelty - first mathematical model for the calculation of the energy parameters of the cold spraying process using original nozzle geometries is developed, developed a new method for the design of divergent part of cold spraying nozzles, developed a new method for the calculation of particles temperature during their impact on the substrate, a new approach for de development of technological recommendations based on a correlation map used to analyze the effect of the process parameters with the coatings properties; implementation degree - results are implemented in National aerospace university "KhAI", JSC "Motor Sich"; field of use - aviation, automobile, medicine industries.
