Résumé

Silicon element plays an important role in strength and hardness improvement in steels, but is harmful for ductility, tenacity, and anti-corrosion. Therefore, silicon content should be fast determined in steel manufacture to keep silicon in moderation. In this work, micro laser-induced breakdown spectroscopy assisted with laser-induced fluorescence (μLIBS-LIF) was proposed to sensitively determine silicon in low-alloy steels. The mechanism and excitation selection of laser-induced silicon atomic fluorescence in laser-induced plasma were discussed. Under 10 µm laser-ablated scatters, the results showed that μLIBS-LIF had analytical performance with R
