Influence of Electrical Parameter on the Size of Superalloy Powders Prepared by Spark Plasma Discharge Process

Abstract:

Superalloy powders, which have a small particle size and spherical shape, were prepared by a spark plasma discharge process. The electrical parameter, spark voltage, current and pulse duration have very important effects on the size distribution of produced superalloy powders. When current or pulse duration changed the mean size significantly changed.
