Plasma Treatment of Metallic Artefacts

Plasma Treatment of Metallic Artefacts

Abstract

The plasma chemical removal of the corrosion layers from archaeological artifacts by RF hydrogen low pressure plasma is a relatively new technique discovered at mid 80's. Because each object is original with the unique composition of corrosion layers as well corrosion history the model corroded samples were used for the presented study. The different duty cycles were applied to keep low temperature of samples. The second plasma application in the conservation is deposition of thin layers protecting the objects from the secondary corrosion. The organosilicone and parylene thin films were applied.
