RESUMEN: La Catedral de Toledo se edificó en un período de más de 200 años, bajo numerosos criterios de construcción que se reflejan en la multiplicidad de estilos que alberga (entre mudéjar y gótico, con aportaciones flamencas, barrocas y renacentistas). A través de los siglos, ha sido objeto de numerosas restauraciones, también bajo distintos criterios. La catedral está ubicada en un ambiente poco agresivo, en cuanto a corrosión atmosférica se refiere. Sin embargo, el discurrir de tantos años no deja de hacer mella en los diversos elementos estructurales, arquitectónicos y artísticos que la componen. En recientes restauraciones se obtuvieron algunos elementos metálicos que han estado expuestos, por muchos años, siglos inclusive, a las inclemencias del clima toledano, con el propósito de analizar su composición y deterioro, empleando las técnicas de Microscopio Electrónico de Barrido con Microsonda de Rayos-X (SEM/EDAX), Espectroscopia Fotoelectrónica de Rayos X (XPS) y Difracción de Rayos-X (XRD). Dichos elementos son: una cubierta, una grapa de sujeción, un clavo y un elemento para sujetar vidrieras.
ABSTRACT: The construction of Toledo Cathedral spanned a period of more than 200 years and was influenced by many different trends and criteria, reflected in the wide range of styles it accoramodates (basically Mudejar and Gothic, with Fiemish, baroque and renaissance elements). Over the centuries it has undergone numerous restorations, also according to different criteria. The cathedral is situated in an environment of low aggressivity, in terms of atmospheric contamination, but the passage of time has taken its toll on many srructural, architectural and artistic elements. During recent restoration work several metallic elements, which have bcen exposed for many years or even centuries to the inclemencies of the Toledo climate, were taken in order to analyse their composition and deterioration. The techniques used have been Scanning Electron Microscopy with X-Ray Microprobe (SEM/EDAX), X-Ray Photoelectron Spectroscopy (XPS) and X-Ray Diffraction (XRD). The elements considered are a piece of roofing lead, a lead slate clamp, a piece of stamed glass window leading, and an iron nail
