dc.description.abstractThe Pinacoteca de São Paulo has a collection of artworks by Brazilian artists dating from the 17th century to the present. An important part of the collection consists of weathering steel sculptures displayed in different internal and external spaces. Besides offering good resistance to corrosion, weathering steels are extensively used in outdoor sculptures and built structures, due to its attractive appearance and self-regenerating capacity. By identifying the materials that compose an artwork and the phenomena that might occur on a given surface, it is possible to carry out preventive conservation actions in the short, medium and long terms. Initially, a visual analysis was performed on each individual work, as well as an accurate identification of the metals with the aid of handheld X-ray fluorescence spectrometry (XRF). Afterwards samples were collected for scanning electron microscopy (SEM) and X-ray diffraction analysis, which identified different oxides formed on their surfaces. In order to obtain more precise results regarding the elements that compose the works, a new process of identification in situ was carried out using X-ray fluorescence spectrometry (XRF). The results reveal the predominance of goethite α-FeOOH, lepidocrocite γ-FeOOH and akaganeite β-FeOOH which shows the influence of the environmental conditions to which the artworks are exposed in the formation of the oxides that form the superficial patina. Moreover, the findings also point to the identification of akaganeite in a number of works where the conditions of the natural environment are not usually favourable for its formation. From this study it was possible to identify the environmental conditions in which the works suffer greater deterioration and the actual causes of this deterioration, enabling future actions and decisions concerning to the preventive conservation of these works, such as not applying coats of wax or varnish for protection.eng
