In this work, an engine valve composed of different alloys has been analyzed by laser- induced breakdown spectroscopy to prove the capability of this technique to characterize mechanical parts which are complex in terms of shape and composition. With the acquired spectral data, 3D chemical maps have been plotted using a computer application for four representative elements: Fe, Cr, Ni and Mn. In addition, information about the in-depth distribution of Cr and Fe in different parts of the valve is shown. Results prove the potential of this technique to be implemented as an evaluation tool for quality control.
