Brusadin, C. Iacovella, G. Modesti, M. Bernabei Aeronautica Militare - Centro Sperimentale di Volo - Reparto Chimico (Aeroporto M. De Bernardi - Pratica di Mare – Pomezia, Roma) The aim of this study is the characterization of metal materials by the quantitative chemical analysis of aeronautical massive samples performed with the XRF technique and comparing this technique with the ICP-OES and FESEM-EDS techniques.

The XRF technique, already normed for High Alloy Steels ( UNI EN 10315:2006 ), can be performed also for Aluminium and Titanium alloys. QUANTITATIVE ANALYSIS performed by the XRF technique allows to determine the exact chemical composition of metal materials, as well as the ICP-OES, the reference technique used for the characterization of alloys ( UNI EN 10351:2011; UNI EN 14242:2004 ). The XRF technique, already normed for High Alloy Steels ( UNI EN 10315:2006 ), can be performed also for Aluminium and Titanium alloys. SEMI-QUANTITATIVE ANALYSIS can be performed by XRF technique as well as EDS microanalysis for screening analysis of unknown metal samples. The XRF technique, operating at a higher power respect to the EDS, gives an error measure lower than that obtained with the EDS.
