Gas-Substrate Heat Exchange During Cold-Gas Dynamic Spraying

Journal of Thermal Spray Technology, 2012
Abstract In this study, the temperature distribution of the surfaces of several substrates under an impinging gas jet from a cold spray nozzle was determined. A low-pressure cold-gas dynamic spraying unit was used to generate a jet of hot compressed nitrogen that impinged upon flat substrates. Computer codes based on a finite differences

Gas Dynamic Principles of Cold Spray

Journal of Thermal Spray Technology, 1998
This paper presents an analytical model of the cold-spray process. By assuming a one-dimensional isentropic flow and constant gas properties, analytical equations are solved to predict the spray particle velocities. The solutions demonstrate the interaction between the numerous geometric and material properties.
