| Sumario: | This paper describes the procedure developed for the accurate analysis by ICP-AES of Co-base superalloys, using yttrium as an internal standard. The chemical composition of these materials makes the development of spectroscopic analytical methods difficult due to the presence of major elements that exhibit intense and complex ICP emission spectra. A quantitative sample dissolution procedure and careful selection of the analytical lines used was carried out. The elements investigated were Co, Cr, Ni, W, Fe, Ta, N b, Al, Mo and Mn. Synthetic solutions were used for calibration, and standard samples were analysed to demonstrate the precision and accuracy of the developed method |
