Chaotic Behavior of Plasma Surface Interaction. ATable of Plasma Treatment Parameters Useful to theRestoration of Metallic Archaeological Objects

摘要

In Plasma Physics laboratory of N.C.S.R. "Demokritos" the plasma chemistry method has been used for the restoration and conservation of metallic archaeological objects during the last decades. The obtained experience had led us to conclude that plasma parameters and different status of treated objects are so specific, so as to become unique. In the present paper the theoretical and experimental results of our laboratory are summarized. A treatment table of plasma parameters is given, which claims to be useful for the conservators. It is obvious that this treatment table needs to be completed and extended, so that it meets the uniqueness of each artifact. A theoretical study and the treatment of a variety of iron objects are presented.
