Abstract (en)
[origin: EP1925693A2] Cold projection of powder materials comprises feeding powder materials with different properties into subsonic and/or supersonic parts of a supersonic nozzle via different feed points. The powder materials are accelerated by a gas stream and are deposited on a surface. An independent claim is also included for a device for cold projection of powder materials, comprising an electric heater (1) for heating pressurized gas, a supersonic nozzle (2) connected to the outlet of the heater, a principal feed device for supplying the nozzle separately with at least two powders, and at least one supplementary feed device for supplying the supersonic parts of the nozzle with at least one powder.
