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.
