Resumen

Los aceros patinables han sido ampliamente utilizados debido a la habilidad protectora de la herrumbre que se forma en la superficie del metal al exponerlo a la atmosfera. Su estudio se ha enfocado en las especificaciones y características desde un punto de vista ingenieril, sin embargo, en patrimonio cultural el uso de este material no sigue los mismos criterios y tiene distintas necesidades que han de atenderse. Entre ellas, el diseño y la localización de la escultura pueden tener un impacto en la herrumbre formada y esta puede no ser tan protectora como se supondría.

Este trabajo presenta el estudio de la escultura de acero patinable Once Módulo la cual muestra áreas con distinta exposición al agua de lluvia y distintas heterogeneidades superficiales. Los resultados del análisis con Espectroscopia de Impedancia Electroquímica (EIE) han mostrado que la habilidad protectora de la herrumbre depende de las diferencias anteriores y que el diseño y la localización de la obra juegan un importante papel en su conservación.

Ana Crespo Ibañez, Centro Nacional de Investigaciones Metalúrgicas (CENIM) – Consejo Superior de Investigaciones Científicas (CSIC)

Ana Crespo obtained her bachelor degree in Chemistry with specialization in Chemistry of Materials in 2011 from the Complutense University of Madrid. During her bachelor she started the study of materials in cultural heritage with the project “Spectroscopic analysis of additives of concrete” at the Institute for the Structure of Matter. She continued her academic training with the master degree in Materials Science and Engineering in 2013 from Carlos III University of Madrid, where she obtained the award of basic science and engineering for the design of a portable electrochemical cell with gel-electrolyte, carried out at the CENIM. After working in the UK she returned to Spain to start her PhD at the CENIM with the project “Characterization and evaluation of artificial patinas in weathering steel sculpture”. Her work is focused on the study of natural and artificial patinas in weathering steel sculpture with Raman spectroscopy and electrochemical techniques. During her PhD she made an internship at Commissariat à l’energie atomique de Saclay (France) studying Raman mapping and EDS analysis in rust; she has participated in 8 national and international projects, 1 of them as principal investigator at the synchrotron SOLEIL; 8 publications in congress, 7 of them international; she has collaborated in specialized training courses and postgraduate courses with Carlos III University of Madrid, Pablo de Olavide University of Seville, Menéndez Pelayo International University. She is currently writing her PhD thesis that hopefully will be finished at June 2020.

Postdoctoral researcher in the group “Corrosion and Protection of Metals in Cultural Heritage and Construction (COPAC)” at the Nacional Centre for Metallurgical Research (CENIM-CSIC), Madrid, Spain. After receiving her BA in Fine Arts (conservation), she graduated in Chemistry at the Complutense University in Madrid and completed her PhD in Materials Science and Engineering at the Carlos III University in Madrid. Her research is focused in the application of electrochemical techniques for conservation assessment and diagnosis in metallic cultural heritage and her doctoral thesis has been dedicated to the development of an electrochemical cell for in situ measurements on cultural heritage. She is also involved in several projects, networks and activities related to Heritage Science such as the Spanish Network of Science and Technology for the Conservation of Cultural Heritage (TechnoHeritage), the National Plan for Research Conservation in Cultural Heritage (PNIC), CSIC´s Interdisciplinary Thematic Platform Patrimonio Abierto: Investigación y Sociedad, PTI-PAIS (Open Heritage: Research and Society) or the Spanish Node of the Research Infrastructure for Heritage Science (ERIHS.es).

Iván Díaz Ocaña, Centro Nacional de Investigaciones Metalúrgicas (CENIM) – Consejo Superior de Investigaciones Científicas (CSIC)

He received his Bachelor’s degree in materials chemistry and his PhD, with a distinction “cum laude”, from the Complutense University in Madrid. His doctoral thesis was one of the first in-depth research conducted in Spain on atmospheric corrosion of weathering steels, incorporating nickel in its composition. During his PhD, he received several pre-doctorate research scholarships to complete his training in the characterization of rust at the Old Dominion University (USA) and University of Antioquia (Colombia). He has a solid background in electrochemical and accelerated corrosion tests and its research focus is on indoor and outdoor atmospheric corrosion of metals. As a result, he has published around 40 research papers in peer-reviewed journals in the field of atmospheric corrosion and has carried out scientific-technical assistance tasks for the industry.

Currently, he is working as postdoctoral researcher in the group “Corrosion and Protection of Metals in Cultural Heritage and Construction (COPAC)” at the Nacional Centre for Metallurgical Research (CENIM-CSIC), Madrid, Spain.

Emilio Cano, Centro Nacional de Investigaciones Metalúrgicas (CENIM) Consejo Superior de Investigaciones Científicas (CSIC)

Emilio Cano is Tenured Scientist at the National Center for Metallurgical Research (CENIM) of the Spanish National Research Council (CSIC) in Madrid, leading the research group “Corrosion and Protection of metals in cultural heritage and construction” (COPAC). He graduated in Fine Arts Conservation in 1996 and obtained his PhD in 2001 from the Complutense University of Madrid, after an internship at the Canadian Conservation Institute (CCI), Ottawa.

As heritage scientist, his work has focused in the study of corrosion and protective systems for the metallic Cultural Heritage, atmospheric corrosion in museums and exhibitions; and the application of electrochemical techniques and corrosion inhibitors for the conservation of the cultural heritage.  He has published more than 125 scientific articles (88 in JCR/Scopus indexed journals), and presented at more than 100 scientific conferences. He has participated in 33 national and international research projects (6th and 7th Framework Programmes and Horizon 2020 from the EU), being PI in 14 of them in the last 10 years. These projects and several research contracts have been developed in collaboration with the most relevant institutions working on conservation of cultural heritage (Instituto del Patrimonio Cultural de España, Patrimonio Nacional, Museo del Prado, Museo Guggenheim Bilbao, Museo Arqueológico Nacional, Museo Nacional de Ciencia y Tecnología, etc.).

Spanish Representative in the Executive Board of the Joint Programming Initiative “Cultural Heritage and Global Change: a Challenge for Europe” from 2011-2017. Assistant Coordinator of the International Council of Museums-Conservation Committee (ICOM-CC) Metal Working Group since 2012; Coordinator of the Spanish Network for Science and Technology for the Conservation of Cultural Heritage (Technoheritage) since 2015, Fellow of the International Institute of Conservation (IIC) and member of the Spanish group of the IIC (GE-IIC); coordinator of the Spanish Node of the European Research Infrastructure on Heritage Science (E-RIHS).
