“…However, the detection of only the elemental composition is a strong limitation for this kind of study. Therefore, the use of the technique is suggested as a first approach, while a multi-technical study is advisable for the identification of the compounds, as reported in [28]. For this reason, the INFN-CHNet group is involved in the development of instruments and techniques to support conservation processes, characterisation, and dating techniques in the heritage science field.…”

The Importance of Being Versatile: INFN-CHNet MA-XRF Scanner on Furniture at the CCR “La Venaria Reale”

At present, the use of non-destructive, non-invasive X-ray-based techniques is well established in heritage science for the analysis and conservation of works of art. X-ray fluorescence (XRF) plays a fundamental role since it provides information on the elemental composition, contributing to the identification of the materials present on the superficial layers of an artwork. Whenever XRF is combined with the capability of scanning an area to provide the elemental distribution on a surface, the technique is referred to as macro X-ray fluorescence (MA-XRF). The heritage science field, in which the technique is extensively applied, presents a large variety of case studies. Typical examples are paintings, ceramics, metallic objects and manuscripts. This work presents an uncommon application of MA-XRF analysis to furniture. Measurements have been carried out with the MA-XRF scanner of the INFN-CHNet collaboration at the Centro di Conservazione e Restauro “La Venaria Reale”, a leading conservation centre in the field. In particular, a chinoiserie lacquered cabinet of the 18th century and a desk by Pietro Piffetti (1701–1777) have been analysed with a focus on the characterisation of decorative layers and different materials (e.g., gilding in the former and ivory in the latter). The measurements have been carried out using a telemeter for non-planar surfaces, and with collimators of 0.8 mm and 0.4 mm diameter, depending on the spatial resolution needed. The combination of the small measuring head with the use of the telemeter and of a small collimator has guaranteed the ability to scan difficult-to-reach areas with high spatial resolution in a reasonable time (20 × 10 mm2 with 0.2 mm step in less than 20 min).

“…The INFN-CHNet MA-XRF scanner has recently been employed on furniture. This further application is particularly interesting since, at the present time, the literature on XRF analysis on furniture is still poor [26][27][28], and no cases of MA-XRF analysis on furniture have been reported.…”

“…To identify the presence of manganese, the PyMCA program was used because only through the analysis of EDS through the Quantax program it was not possible to certify the existence or not of manganese, since the element is present in low alloy concentration and its primary peak overlaps the secondary one of chromium, and secondary to the iron primary, elements present in higher quantities and by PyMCA program, it can be built a multi-element calibration to determinate an specific element well-characterized in terms of precision extracting the spectra of arbitrary regions on the maps (Heginbotham and Solé, 2017;Felix, et al, 2018;Freitas, et al, 2019).…”

The Brazilian thermoelectric plants that use coal as a thermal source use pulverized combustion technology. The aim of this work was to characterize some properties of a metallic coating obtained by arc electric thermal spray in order to protect boiler's surface against ash's aggressive action from coal burning. The evaluated parameters considerably influence the characteristics of the coating's lifes service. An iron chromium base alloy, reference herein as Alloy B, was used in this study. A chemical analysis of the coating, Alloy B, was performed in order to compare if there were any difference between the chemical composition of the wires used and what was incorporated into the coating by the thermal spray process. Therefore, Energy Dispersive Spectroscopy technique (EDS), Quantax software and PyMCA program were used. The chemical analisys results of the coating was quite similar to the given composition of the wires. To verify the coating hardness, Vickers (HV) microhardness measurements were performed on the coating region, on the substrate and on the boundary region of the coating between substrasts. Vickers microhardness measurements were obtained by PANTEC MV-1000A microdurometer. As substrate an 8 mm thick steel sheet with a chemical composition and thickness similar to the steels used in the water wall pipes of Brazilian boilers were used. The coating hardness (730 HV) was on the order of four times greater than the substrate's hardness (179 HV) to be protected. This property was homogeneous for the coated layer showing that hardness values indicates that good adhesion of coating's cast particles occurred, and the spray distance proved to be effective. The roughness was obtained through measurements made

“…O processo de fabricação das placas utilizou os mesmos parâmetros que usualmente são usados para a confecção da estrutura suporte do acetato As superfícies das placas sem e com selante, nas diversas composições testadas, foram observadas por estéreo microscopia, microscopia óptica (MO) 12,13 e por eletrônica de varredura (MEV) 12,14 , respectivamente através dos microscópios Olympus modelo 8ZX16, Zeiss modelo M2m e Hitachi modelo TM3000, este último operando a 15kV. Análise e mapeamento dos elementos químicos [15][16][17][18] presentes foi realizada por espectroscopia por dispersão de energia (Energy Dispersive Spectroscopy -EDS) [19][20][21][22][23] utilizando-se um detector X Flash MIN SVE fabricado pela Bruker acoplado ao MEV.…”
