Improved Atomization Processing for Fossil Energy Applications


Project No: FWP-AL-99-501-032


Project Description

During this project, researchers will improve the design of high-efficiency gas atomization nozzles in order to maximize powder yields in special size classes most suitable for thermal-sprayed coatings. Sizes will include ultrafine powders, with particle diameters of less than 10 microns (µm), and mid-range powders, with particle diameters ranging between 10 and 44 µm. Powder production tests will be performed in laboratory atomization systems to demonstrate steady-state operation and controls systems suitable for industrial use. Researchers will perform a detailed analysis of atomization process responses to alloy and parameter modifications to verify the effect of process innovations. Initial work will involve pure metals and simple model alloys for each target area of process or alloy development.
