Evolution of substrate temperature during nozzle movement under cold spraying conditions

Evolution of substrate temperature during nozzle movement under cold spraying conditions Results of a study of the evolution of substrate temperature during nozzle movement under cold spraying conditions are reported. A model for calculating the substrate temperature is proposed and verified. Calculated data for typical ranges of nozzle traverse speed, substrate thickness, and initial substrate temperature encountered in the spraying practice, were obtained. It was shown that there exists an optimum initial substrate temperature at which the variation of temperature in the spray spot proves to be minimal. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Thermophysics and Aeromechanics Springer Journals

Abstract

Results of a study of the evolution of substrate temperature during nozzle movement under cold spraying conditions are reported. A model for calculating the substrate temperature is proposed and verified. Calculated data for typical ranges of nozzle traverse speed, substrate thickness, and initial substrate temperature encountered in the spraying practice, were obtained. It was shown that there exists an optimum initial substrate temperature at which the variation of temperature in the spray spot proves to be minimal.
