Abstract

The coating layer thickness of the double-layer objects was estimated using the concentration value of an element of the covering layer or of the substrate after obtaining suitable calibration curves using reference materials. The x-ray fluorescence technique was used with a handheld instrument to determine the concentration of elements. Various experimental configurations were built using gold- and silver-plated materials. The concentration calibrations curve as a function of coating layer thickness were successfully applied to gold-plated brass and copper jewelry, gold-plated samples and an ancient silver coin. The results obtained using the concentrations are in good agreement with those of other more elaborate methods.
