heal.abstract	The use of laser technology in the cleaning of artworks has a wide range of applications, including the cleaning of metallic objects. The main aim of this work was to investigate the use of lasers in the cleaning of the thin silver plating layers found in late Roman copper alloy coins. Previous work showed that corroded silvered copper alloy coins required different cleaning conditions than other corroded copper coins. In this paper, comparative cleaning tests by means of a Nd: YAG laser (1064 nm, 532 nm and 266 nm) were performed in order to minimize the thermal effects and to minimize the laser absorption depth to the thin layer of corrosion near the surface. The laser-treated surfaces were characterised using Optical Microscopy and Scanning Electron Microscopy (SEM). © 2008 Taylor & Francis Group, London.	en
