Abstract

Laser induced breakdown spectroscopy (LIBS) calibration curves for SnZr and NbZr alloys were obtained. Relationships between the atomic emission lines present in the spectra and the Sn and Nb concentrations of the samples showed a linear behavior. Also Zy-2 standards were measured to contrast the behavior of the technique in different kind of alloys. The choice of proper Sn,Nb and Zr lines and the equipment´s parameters, such as “integration start delay” and the spectrometer height, were fundamental to enhance the measurements. The samples were analyzed by X-ray fluorescence for a precise determination of their Sn and Nb concentrations.

Keywords

LIBS, ZrSn and ZrNb alloys, Calibration curves, Nuclear.

Resumo

Foram obtidos por espectroscopia a laser (LIBS avaria) curvas de calibração para as ligas de SnZr e NbZr. As relações entre linhas de emissão atômica presentes mostraram um comportamento linear. Zy-2 também foram medidos para comparar as regras de comportamento da arte em diferentes tipos de ligas. A escolha de linhas apropriadas de Sn, Nb e Zr e parâmetros de equipamentos, tais como a “integração de atraso da partida” e a altura do espectrômetro, foram fundamentais para melhorar as medições. Todas as amostras foram analisadas por fluorescência de raios para uma determinação exata das concentrações de Sn e Nb.

Palavras-chave
