Determine the Chemistry of Selected Steel by NDE Technique of Positive Material Identification (PMI)

S. Gunasekaran, P. Kuppuraj, K. Priya

Abstract: A great number of procedures have been developed and today a wide assortment of special analytical equipment for the analysis of chemical compositions of metal and alloys, including those widely spread and industrially produced, exists [1]. However, new analytical tasks for the control of steel products, or for individual parts made from them, constantly appear, and it is sometimes difficult to choose the appropriate method and device for the analysis. Very often complications appear when it is necessary to test a finished product, which must be left in for further use. The analysis must then be performed, or the sample taken, in such a way that the object does not loose its technical assignment or demand future restoration or repair. In addition, the more important and the more expensive the object, the less damage there must be and, at the same time, the more accurate the analysis must be. As a rule, these two conditions contradict each other. The list of objects requiring strict control of their composition is long: boilers, which operate under high pressure, and supplementary equipment; tanks for keeping fuel, lubricants and flammable materials; load-lifting or transportation mechanisms, cranes, and so on [2]. These problems are accelerated to the researchers of Metal chemist and got solutions i. e. Identification of Positive Materials by XRF Techniques of Non Destructive Test and Evaluations (NDE). Often, famously it has called Positive Material Identifications (PMI). It is known that non-destructive control of the composition can be conducted by X-ray analysis and portable compact analyzers have been created for performing analyses under field conditions. Based purely on physical features, X-ray fluorescence analysis is realized in high-quality laboratories. In this present study, we would like to develop a procedure for analyzing some selective industrially used steel products using XRF Spectra i. e. PMI and the same comparatively analyzing by Optical Emission Spectrometer (OES) and Wet Chemistry and also verify the obtained results to prove the best one for NDE.
