Failures of mechanical systems are often due to material exchange or to compositions outside specifications. So the check ot the alloy composition is often required in ordre to master the subsequent processes.
Several years ago, Laboratoire Dubois acquired a spark spectrometer. Configured for the analysis of iron, aluminium, copper, nickel, cobalt, tin, lead and titanium alloys, this equipment can be used to quantitatively measure the amount of alloy elements as well as impurities.
Carbon, sulphur, phosphorus, nitrogen and boron are among the analysable elements. The advantage of this technique lies in the fact that there is no need previous dissolution of the alloy, thus enabling a rapid and cost-effective analysis.
