Deterioro y estrategias de conservación de elementos metálicos de interés patrimonial de la estación de ferrocarril de Aranjuez

摘要

The conservation state of metallic structures (shelters) of platforms and travellers building of the railway station of Aranjuez has been evaluated. The objectives include the diagnosis of processes and mechanisms of deterioration, degradation and corrosion occurred, as well as the best intervention and preventive conservation criteria for correct preservation. Metallic materials are the real protagonists of the Aranjuez station architectural style and possess notable historical interest. Their macroscopic and microscopic pathologies were determined by using optical microscopy and field emission scanning electron microscopy. Likewise, an analytical study by X-ray diffractometry, metallography and X-ray energy dispersive spectrometry was carried out. Experimental results clarified the chemical-physical degradation processes, the intervention recommendations and preventive conservation guidelines.
