Application of Plasma in the Field of Cultural Relics Protection

Abstract

Many ancient cultural relics are unearthed every day around the world, and once unearthed, these relics face the risk of corrosion and mineralization. How to effectively protect these relics is a very difficult problem for researchers in the field of archaeology. In the field of cultural relics preservation, the application of plasma glow discharge can effectively remove harmful rust on the surface of excavated cultural relics and prevent further corrosion from the harmful rust. In order to remove harmful substances from the surface of cultural relics and achieve the goal of cultural relic protection, using hydrogen, argon and other gases to glow discharge in a plasma device to treat cultural relics placed inside. This is a novel method for cultural relic preservation. Compared to traditional chemical preservation methods, it offers advantages such as shorter processing time and the ability to retain the original appearance of the artifact. In this paper, the fundamental components of the plasma treatment device were elaborated upon, and the basic principles of using different plasma atmospheres to treat cultural relics of different materials were described. A novel approach for the protection of excavated cultural relics was thus presented. In the future, the form of plasma treatment devices and the exploration of various treatment gas atmospheres will hold significant research value.
