1 Feb 2018 | Abstract: | Powder materials utilized in additive technologies were quantitatively
analyzed by laser induced breakdown spectroscopy for the first time. Laser
induced breakdown spectroscopy mapping of loose metal powder attached to the
double-sided adhesive tape provided high reproducibility of measurements even
for powder mixtures with large difference of particles densities (tungsten
carbide particles in nickel alloy powder). Laser induced breakdown spectroscopy
analytical capabilities for tungsten and carbon analysis were estimated by
calibration curve construction and accuracy estimation by leave-one-out
cross-validation procedure. Laser induced breakdown spectroscopy and X-ray
fluorescence spectroscopy techniques comparison revealed better results for
laser induced breakdown spectroscopy analysis. Improved accuracy of analysis
and capability to quantify light elements (carbon etc.) demonstrated large
perspectives of laser induced breakdown spectroscopy as a technique for express
on-site multelement analysis of powder materials utilized in additive
technologies. | Source: | arXiv, 1802.0236 | Services: | Forum | Review | PDF | Favorites |
