Protection of Archaeological Artefacts by Deposition of Parylene and SiOx Thin Films
Original language description
The treatment process of archaeological artefacts is usually divided into two main steps. A surface corrosion removal is the first step that is performed by low pressure hydrogen plasma. Its chemically reducing atmosphere allows a careful removal of corrosion without damaging the artefact surface details. After the procedure, the surface is highly reactive and inclines to oxidation. To prevent this process, it is necessary to protect the surface with a barrier film preventing the penetration of oxygen (as well as the other corrosion agents) to the surface. This study focuses on possibilities of the archaeological artefacts (copper, iron, brass and bronze) protection by a thin film deposition of SiOx and Parylene thin films. Parylene (poly-para-xylylene) is used in a wide range of applications, particularly as a coating for biomedical implants and microelectronics. Parylene coatings are chemically inert, conformal and transparent with excellent barrier properties [1] but relatively smal
