Indoor atmospheric corrosion of lead pipes is a severe problem affecting European historical organs. The action of the organic acid vapours emitted by the wood structures is known to be one of the main causes accountable for lead corrosion. In the frame of the COLLAPSE (Corrosion of Lead and Lead-tin Alloys of Organ Pipes in Europe) research project, samples from different organ pipes have been analysed by Optical Microscopy (OM), Stereo Microscopy (SM), X Ray Diffractometry (XRD), Scanning Electronic Microscopy (SEM) with EDS analyses and Fourier Transform Infrared Micro-Spectroscopy (FTIR). On the basis of the results, compositional and microstructural factors influencing the corrosion resistance have been identified.

Abstract
Indoor atmospheric corrosion of lead pipes is a severe problem affecting European historical organs. The action of the organic acid vapours emitted by the wood structures is known to be one of the main causes accountable for lead corrosion. In the frame of the COLLAPSE (Corrosion of Lead and Lead-tin Alloys of Organ Pipes in Europe) research project, samples from different organ pipes have been analysed by Optical Microscopy (OM), Stereo Microscopy (SM), X Ray Diffractometry (XRD), Scanning Electronic Microscopy (SEM) with EDS analyses and Fourier Transform Infrared Micro-Spectroscopy (FTIR). On the basis of the results, compositional and microstructural factors influencing the corrosion resistance have been identified.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
