Determination of Aluminum in Nickel-based Superalloys by Using Laser-Induced Breakdown Spectroscopy

    Graphical Abstract
    • Abstract
  • Laser-induced breakdown spectroscopy (LIBS) was developed to detect aluminum in nickel-based superalloys (K417, GH4033, DZ125L, Эп742у) using a non-intensified, non-gated, low-cost detection system. The precision of LIBS depends strongly on the experimental conditions. The calibration curves of Al(Ⅰ)394.4nm and Al(Ⅰ)396.2nm under the optimum experimental parameters are presented. Finally the limit of detection (LOD) for aluminum is calculated from the experimental data, which is in the range of 0.09% to 0.1% by weight.
