Comparison of Wet and Dry Laser Cleaning of Artworks
This paper presents results of numerical calculations of graphite (model medium for black encrustation) removal from aluminium (model medium for artwork substrate) using laser ablation method. Theoretical comparison of cleaning rate of graphite as a solid encrustation as well as porous graphite filled with air or water, using pulsed laser radiation, are presented. Moreover, results of numerical modeling of pressure pulse, generated by laser pulse in graphite filled with water, are shown.
