An Experimental Study on Using Laser for Cleaning Metal Threads

Abstract

Samples of metal threads were prepared, underwent artificial aging, and cleaned using laser applications to define the efficiency of cleaning that gives the best results without affecting the components of the thread, including metal, fibers, or dyes. The present study aimed to investigate and evaluate laser cleaning of the corroded metal embroidery, revealing the chemical composition of the corrosion and prop and evaluating the effects of laser cleaning on the surface of the metal threads. It utilized SEM and LM to provide morphological information about the surface and the cleaning effect. Moreover, SEM-EDX was used to define the elemental composition, and XRD was employed to offer information on the metal. The restoration of cultural heritage depends on defining the devastating changes to the man-made pieces. It compares pre-and post-restoration conditions of the object (e.g. painting, photography, and material analysis), controlling the conditions that are almost irrevocable. An Interval Digital Macro-photography is employed to control the corrosion PS tests for a long period of museum exhibition [1].

Evaluation of Cleaning Soiled Deposits and Crusts from Archaeological Glass Using Laser Treatment with Ag/Au Nanoparticles

“…Recently, laser technology has been presented as a brand-new cleaning method for preserving cultural heritage artifacts, either as a supplement or a replacement for traditional methods. Laser cleaning has proven successful in the process of cleaning cultural heritage materials in general over the past forty years, as it has been successful in the process of cleaning various artifacts, whether organic, such as textiles, paper, and manuscripts, or inorganic, such as glass, ceramics, metals, and stones [16][17][18][19]. This technique helps maintain the surface of various archaeological materials by removing damaging reactive corrosion products in a very selective, non-contact manner.…”
