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

9461971哈希什这个小型企业创新研究(SBIR)第一阶段项目将探索一种新的低成本雾化工艺，从金属合金中制备超细粉末。该工艺使用超高压(UHP)水射流雾化熔化的预合金金属。虽然水已经用于一些金属雾化过程，但这种使用高达100,000磅/平方英寸的超高压水射流的方法与目前的方法有很大的不同。高能水射流需要的水要少得多，这将导致一个几乎干涸的过程和一个更小的过程系统。还将探索超高压氮气喷嘴。由于设备紧凑，以及该工艺的高效率和高产量，生产超细粉末的雾化成本预计将会降低。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.
