Visualization of particle jet in cold spray by infrared camera: feasibility tests

Visualization of particle jet in cold spray by infrared camera: feasibility tests In this article, the feasibility study of application of the infrared camera for visualization of the particle jet in cold spray was performed. Stainless steel particles accelerated by the standard cold spray nozzle at spray parameters typical for cold spray deposition were used in experiments. Experimental results show that the infrared camera is capable to detect the particle trajectories due to significant temperature contrast and could be used as a robust technique for the powder trajectory visualization. Image treatment procedure allows to provide the particle jet profile at different distances from the nozzle exit. Obtained frames confirm the presence of particle collisions in the nozzle as well as in the free jet. Additional particle track velocimetry (PTV) measurements showed that the particle velocity in experiments was in the range 500–700 m/s that are the typical values for cold spraying of stainless steel powder. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png The International Journal of Advanced Manufacturing Technology Springer Journals

Abstract

In this article, the feasibility study of application of the infrared camera for visualization of the particle jet in cold spray was performed. Stainless steel particles accelerated by the standard cold spray nozzle at spray parameters typical for cold spray deposition were used in experiments. Experimental results show that the infrared camera is capable to detect the particle trajectories due to significant temperature contrast and could be used as a robust technique for the powder trajectory visualization. Image treatment procedure allows to provide the particle jet profile at different distances from the nozzle exit. Obtained frames confirm the presence of particle collisions in the nozzle as well as in the free jet. Additional particle track velocimetry (PTV) measurements showed that the particle velocity in experiments was in the range 500–700 m/s that are the typical values for cold spraying of stainless steel powder.
