简介：We present the results of laser ablations cleanness process on bronzes covered by a chloride patina in two different media:marine water and air. The bronze chloride disease was obtained treating commercial bronzes with HCl 37%, for 190 h. X-ray photoelectron spectroscopy and optical images taken on treated samples show the formation of a CuCl2/Cu2Cl2 patina of about 300 m.Laser ablation reduces in both medium the patina thickness at few microns without changing the chemical composition of bronze.
