The process uses ultrahigh-pressure (UHP) waterjets to atomize molten pre-alloy metals. Although water is already used in some metal atomization processes, this method of using UHP waterjets up to 100,000 psi represents a significant departure from current methods. Highly energetic waterjets will require much less water, which will result in a nearly dry process and a smaller proceqsing system. UHP nitrogen jets will also be explored. The costs of atomization, for production of ultrafine powders, is expected to be reduced due to compactness of the equipment and to the high efficiency and high yields of the process. Materials-processing applications, among others,in injection molding and ceramic powder operations.
