Thermal gradient of in-flight polymer particles during cold spraying

[Display omitted] •Discontinuous nozzle induces the flow to choke at the discontinuity location.•At the nozzle exit, the particle velocity reaches 190 m.s−1 for 60 μm diameter.•During cold-spray, polymeric particles are submitted to important thermal gradient. The manufacture of polymer coatings via...
