A couple of additional cooling nozzles were assembled under traditional atomization nozzles in order to improvethe process and produce the powder with fine microstructure and low oxygen. The influence of the process parameters onthe properties of the powder was investigated. The results show that finer powders with lower oxygen content and more ir-regular shape can be achieved by combinatorial atomizing process comparing with normal one under the same atomizingpressure.
