Abstract

The invention relates to a cold gas spraying pistol in which the powder injection tube (4) terminates more than 40 mm before the nozzle neck, at which the convergent nozzle section (1) transforms into the nozzle outlet (2). By means of the above powder injection at least 80 wt. % of the particles achieve a nozzle inlet temperature which is 0.7 times the nozzle inlet temperature of the gas stream in Kelvin.
