کاربرد لیزرهای Nd:YAG و ۲CO در پاکسازی خوردگی اشیاء برنزی و مسی تاریخی

As in restoration and conservation of historical objects removing the corrosive salts from historical metal surfaces is important, the application of two types of lasers for removing corrosive salts from several historical copper and bronze species has been investigated. The purpose of this research is to compare the results of Nd:YAG and CO۲ lasers application with defined pulses and energies in removing corrosive salts. Two mechanisms including dry laser and steam laser cleaning have been used. Also, the traditional methods (chemical and mechanical) have been used to compare the results of the cleaning. The applications of the applied lasers have been shown that CO۲ laser at ۱۰.۶mm gives the best results.
