“…The authors claimed an improvement in accuracy following application of this approach. A new commercially available mobile system that combined the XRD with XRF techniques was evaluated by de Voorde and colleagues 14 for the identication of pigments in cultural heritage artefacts. The instrument incorporated copper or molybdenum miniature X-ray tubes and a Si(PIN) detector and was tested successfully in the characterisation of lead alloy printing letters.…”

“…The parameters are shown in Table 3. The feedstock cored wire, the arc-sprayed coating as well as the droplet were firstly subjected to XRF analysis in a Fischerscope X-ray XAN device (year 2005) [1][2][3]. This device does not need any sample preparation and provides direct qualitative measurement in less than one minute.…”

Abstract. In wire arc spraying, the raw material needs to exhibit sufficient formability and ductility in order to be processed. By using an electrically conductive, metallic sheath, it is also possible to handle non-conductive and/or brittle materials such as ceramics. In comparison to massive wire, a cored wire has a heterogeneous material distribution. Due to this fact and the complex thermodynamic processes during wire arc spraying, it is very difficult to predict the resulting chemical composition in the coating with sufficient accuracy. An Inconel 625 cored wire was used to investigate this issue. In a comparative study, the analytical results of the raw material were compared to arc sprayed coatings and droplets, which were remelted in an arc furnace under argon atmosphere. Energy-dispersive X-ray spectroscopy (EDX) and X-ray fluorescence (XRF) analysis were used to determine the chemical composition. The phase determination was performed by X-ray diffraction (XRD). The results were related to the manufacturer specifications and evaluated in respect to differences in the chemical composition. The comparison between the feedstock powder, the remelted droplets and the thermally sprayed coatings allows to evaluate the influence of the processing methods on the resulting chemical and phase composition.
