“…The results can play role in elemental material analysis, especially in archaeometry. Silver and copper are used in jewelry and minting from antique times [ 39 , 58 , 59 , 60 ]. Thus it is in the interest of archaeologists to explore the ancient technologies of silver jewelry production.…”

“…Another advantage of

X-ray intensity ratio studies is that this parameter can be used for determination of depth profile distributions of the elements in thick targets [ 40 ]. This technique can be used in archaeometry to determine the silver enrichment taking place in antique silver–copper coins [ 39 , 46 , 47 , 48 ]. Since many decorative objects are composed of silvered copper, gilded copper, or silver, the use of

X-ray intensity ratio from different chemical element can allow estimating the thickness of the surface layer [ 49 ].…”

The numerical simulations of Cu Kα and Cu Kβ fluorescence lines induced by Rh X-ray tube and by monoenergetic radiation have been presented. The copper Kβ/Kα intensity ratios for pure elements as well as for Ag–Cu alloys have been modeled. The results obtained by use of the FLUKA code, based on the Monte-Carlo approach, have been compared to available experimental and theoretical values. A visible relationship was found between the simulated Kβ/Kα intensity ratios and the copper content of the Ag–Cu alloy: as the Cu content increases, the Kβ/Kα coefficient decreases. The results can play role in elemental material analysis, especially in archaeometry.

“…They are influenced by the depth distribution of the elements and the coating layer. [ 4,5 ] The interaction of X‐rays with a sample with different layers leads to a clear change in the intensity ratio between the different characteristic lines, which can be used to determine the thickness of the different layers. [ 6,7 ] The ratio of the characteristic line intensities of an element in the substrate depends on, and can be also used to measure, the thickness of the coating.…”

Gold‐coating thickness determination on Ag, Cu, Fe, and Pb using a handheld X‐ray instrument

2021

Here, the X‐ray fluorescence technique is used to determine the thickness of a coating layer as well as to analyze the surface of objects. Four metals (Ag, Cu, Fe, Pb) were covered with increasing thicknesses of gold. The measurements were performed with a commercial handheld instrument, X‐SORT (Spectro). In double layers, the thickness of the covering layer was assessed by (a) the ratio between the most intense fluorescence lines of the covered element, (b) a cross‐ratio between two lines of the elements in the two layers, and (c) the ordinary partial least squares (PLS) regression method. In all cases, the curves obtained could be used for the quantitative determination of the thickness. The experimental data followed the theoretical trend even though the values of the attenuation parameters were not always in agreement with the theoretical ones. Comparisons and discussion of the results of the different approaches and also with models in the literature are made. The methods studied were applied to determine the nature of the coating layers of some gilded objects and proved to be suitable for estimating the thickness of gold by providing results that were in good agreement with each other.
