Abstract

Titanium alloys (TiAs) have significant applications in engineering and technological purposes but often demand inclusive characterization due to their different components and properties. While previous LIBS investigations on Ti alloys have demonstrated its capability for elemental identification, they have not systematically explored its application for rapid sorting and recycling of industrially relevant titanium alloys with complex compositions. Our work specifically addresses this gap by applying LIBS to differentiate and classify Ti alloys with varying alloying elements. Pure (T0) and two commercial titanium alloys (T1 and T2) have been investigated using LIBS, XRD, and EDS techniques for fast and exact identification, sorting, and recycling processes. Several strong lines of pure titanium are observed, with clear peaks at wavelengths: 452.91, 444.66, 500.79, 521.49, 525.93, 779.31, 822, 844, and 868 nm. The XRD showed that there were three peaks for T0 and T1 and only two peaks for T2. These samples revealed peaks at 2θ = 43.8, 50.8, and 74.8° corresponding to crystalline planes (111), (200), and (220). Also, Energy dispersion spectroscopy (EDS) is used to provide surface distribution data, while X-ray diffraction (XRD) is utilized for examining the crystalline structures of TiAs. The comparisons between LIBS and other elemental analytical methods recommend using a collective approach of these techniques to obtain more acurate and reliable analysis.
