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