“…The application of lasers in conservation faces the challenge to deal with some issues, among others the preservation of the original surface and the formation of unwanted laser induced alteration layers [26,27]. Most of the previous studies have been focused on the laser irradiation effects, using different wavelengths and pulse duration, on the corrosion layer and on the underlying material after a single laser treatment [28][29][30][31][32][33][34]. However, the effects associated with successive laser cleaning treatments on tarnished silver objects have not been addressed before.…”

a b s t r a c tIn this study we evaluate the laser cleaning of tarnished pure and sterling silver substrates using a nanosecond Q-switched Nd:YAG laser at 1064, 532 and 266 nm. To assess the effects associated with cyclic laser cleaning treatments, several cycles of tarnishing followed by laser cleaning were applied on silver coupons that were characterized by gravimetry, colorimetry, scanning electron microscopy, X-ray photoelectron spectroscopy and micro-Raman spectroscopy. According to the obtained results, none of the three wavelengths is recommended for laser cleaning of pure silver objects, while for sterling silver artifacts, the visible laser wavelength of 532 nm seems the most appropriate.

Metal cultural relics are witnesses to the development of human history and civilization, containing rich value and connotation. Metal cultural relics have existed in the natural environment for hundreds and thousands of years and are facing severe corrosion problems, urgently requiring protection. Cleaning is the primary task of protection for metal cultural relics. Laser cleaning technology has attracted the interest of cultural relics scholars because of non-abrasive, non-contact, high efficiency and applicability to various materials. In order to enhance the understanding and application of laser cleaning technology on metal cultural relics, this paper provides a comprehensive review of the research advancements regarding the history and mechanism of laser cleaning technology, the corrosion mechanism of different metal cultural relics (copper relics, iron relics, silver relics, gold relics), as well as the application achievements of laser cleaning for metal cultural relics. The present study discusses the key problems and the development prospects of laser cleaning technology of metal cultural relics. Ultimately, the article will provide new ideas for the research and practice for the cleaning and protection of metal cultural relics.
