SBIR Phase I: Fabrication of Ultrafine Powders Using Ultrahigh Pressure Fluid Jets

9461971 大麻 该小型企业创新研究（SBIR）第一阶段项目将探索一种新的低成本雾化工艺，用于从金属合金中制备超细粉末。 该工艺使用超高压（UHP）水射流对熔融的预合金金属进行喷射。 尽管水已经用于一些金属雾化工艺中，但是使用高达100，000psi的UHP水射流的这种方法代表了与当前方法的显著偏离。 高能水射流将需要更少的水，这将导致接近干燥的过程和更小的处理系统。 还将探索UHP氮气射流。 由于设备的紧凑性以及该方法的高效率和高产率，用于生产超细粉末的雾化成本有望降低。 材料加工应用，其中包括注塑成型和陶瓷粉末操作。

9461971 Hashish This Small Business Innovation Research (SBIR) Phase I project will explore a new low-cost atomiztion process for making ultrafine powder from metal alloys. 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.
