Device (100) for spraying in the plasma flow has a cathode (102) and an anode (101), between which creates an electric arc, through which is fed pressurized gas exiting through an anode (101) a stream (107) of plasma. Into the stream (107) of plasma with a powdered coating material (106). Throat exit the plasma is formed by an axial bore (110) which máprurez noncircular shape, for example grooved. Beam angle (120) (107) plasma is less than 90.degree ..
