V originále

Laser-induced breakdown spectroscopy (LIBS) has already found its place in many applications for its fast and non-demanding utilization with the capability of real-time in-situ analysis. Typical LIBS spectrum reveals complete elemental information about a sample under study, i.e. chemical fingerprint. Moreover, conditions of laser matter interaction, namely the composition of the sample, its chemical and physical properties as well as the properties of laser beam (its wavelengths, energy, duration, focal spot, etc.), have a great impact on the ablation processes, generation and evolution of laser-induced plasma. In other words, detected spectral features reflect not-only the composition of the sample under investigation but also physical and chemical properties of this sample, such as its hardness, roughness, degree of degradation, etc. In this study, the degradation grade of selected materials was correlated with spectral features of corresponding LIBS measurements. Magnesium was chosen for its applicability in automotive as well as in bone scaffolding, reinforcing iron bars play significant role in civil engineering. Samples were cut into small discs and immersed in corrosive environment under controlled conditions. Then, degraded samples were analysed using LIBS system, while the variation in the degree of corrosion products has great impact on the laser-matter interaction and hence on the properties of LIP. Furthermore, size of the ablation crater was estimated for individual samples and LIP characteristics (electron temperature and electron number density) were determined. LIBS results were additionally controlled using X-Ray Diffraction measurements.
