Laser induced breakdown spectroscopy for analysis of products during its synthesis by coaxial laser cladding

Abstract

The feasibility of quantitative multielemental analysis of a composite wear-resistant coating (nickel matrix reinforced with tungsten carbide) in the process of its synthesis by coaxial laser cladding has been demonstrated. Laser induced breakdown spectrometry (LIBS) probe was developed for online analysis of carbon, tungsten and nickel during the process of application a wear-resistant coating. A good coincidence of the online LIBS measurement results with the results by offline standard methods of analysis (X-ray fluorescence spectrometry, electron energy X-ray dispersive spectroscopy, gas analyzer via oxidizing melting in a ceramic crucible by LECO) was achieved.
Key words: laser induced breakdown spectroscopy, additive manufacturing, laser cladding, tungsten carbide, coating.
