Abstract :
A novel production method of nanosized powder synthesis, namely, pulsed wire discharge has been operated repetitively. The system is designed for the operation in the maximum repetition rate of 1 Hz at the stored energy of 720 J. The discharge is operated automatically under computer-control. In the present study, influence of repetition rate on the characteristics of nanosized AlN powder was studied. The repetition rate was varied from 1 to 40 shot/min. It was revealed that the AlN content in the powders synthesized in the system was 83%, and independent to the repetition rate within the present experiments. The ratio of the production mass of powders to input energy was 180 g·(kW·h)-1.
