RESUMO

The modern industry needs materials having high consumer properties. The performance of materials can be highly increased by using various coatings that allow obtaining high quality surfaces and considerably decreasing consumption and loading of materials. Information on chemical elemental composition and its distribution in coatings and within coating−material interface layers is very important for the coating development and application. In the present work, laser-induced breakdown spectroscopy (LIBS) is applied to analyze chemical composition of the coatings prepared by physical vapor deposition (PVD) of a micrometer range thickness and the coating formed by powder spraying in a short DC arc at atmospheric pressure with the thickness of millimeter range. The LIBS measurements for solids give obvious surface composition data: the surface is irradiated by focused laser beams inducing erosion plumes, emission spectra of which are used for the analysis. Here, the LIBS technique is used to measure the elemental composition of sprayed layers on metal samples to obtain the composition evolution from the sample surface deep into the material.
