In-situ Composition Analysis of Direct Metal Deposition Process using Optical Emission Spectroscopy of Laser Induced Plasma

By: Lijun Song and Jyoti Mazumder Center for Laser Aided Intelligent Manufacturing, University of Michigan The ability to monitor the elemental composition in real time for laser aided rapid manufacturing is essential for both estimation of elemental losses and elemental control. Traditionally X-ray fluorescence (XRF) and energy dispersive X-ray spectroscopy (EDS) have been widely used for […]
