Abstract

PURPOSE:To obtain a mixture of flaky powder with spherical powder, by jetting high-speed gas on a flow of a molten metal and colliding the resulting mist against a prescribed cooling body. CONSTITUTION:Gas is jetted from spray nozzles 13 to convert a molten metal 11 flowing out of a nozzle 12 into mist 15. This mist 15 is collided against the surface of a rotary cooling body 14 so arranged under the nozzle 12 that the interval between the cooling body 14 and the nozzle 12 is varied in the flowing direction of the mist 15. By the collision, the mist 15 is rapidly cooled to obtain a mixture of flaky powder 16 with spherical powder 17. Since the contact area of the particles of the powdery mixture is large, the mixture is sintered even at a low temp. and the density of the sintered body is increased.
