Methods of metal powders production

Centrifugal-Ultrasonic Atomisation (CUA)
method of powder production

The CUA method of powder production (see Figure 1) consists in breakage of the melt owing to vibration of tool 3 connected with magnetostrictive converter 4. The method allows production of high-purity powders with the mean particel dimension 50 mkm at a 22 kHz frequency. The method capacity is 10 to 20 kg of the product per hour. Combination of the US and CHA methods makes it possible to raise the capacity up to 100 kg of the product per hour and to produce powders with the mean particle dimension from 10 to 30 mkm.
