Abstract

The laser cleaning of corroded metals is not easily controllable because it is strongly influenced by a great number of factors, such as the laser parameters (wavelength, pulse width, laser fluence, shot number, etc.) and the material properties (chemical composition, optical characteristics, etc.). In particular, this is a crucial problem in laser cleaning of cultural heritage metals because artifacts are unique and irreplaceable [1, 2], As a result, working below ablation threshold fluence of the metal is a fundamental requirement to avoid damages to bulk.
