Description	Plasma chemical treatment of archaeological artifacts by RF hydrogen low pressure plasma is a relatively new technique developed during the 1980s. The corrosions as well as their removal are a very complex problem. The mechanism of corrosion removal is not fully understood up to now and thus optimal conditions are not known well. Because each archaeological object is original it is necessary to study the influence of processes and discharge conditions using the model corroded samples. The sample heating due to the interaction with RF field created by plasma as well as heating directly by contact with plasma must be decreased as much as possible to protect the material structure changes. On the other hand, particular power is necessary for the creation of plasma with sufficiently high concentration of reactive particles, mainly of atomic hydrogen. Thus the pulsed discharge should be a best way how to solve these antagonistic tasks. Our study was done using model corrosion samples of iron, copper, bronz Plasma chemical treatment of archaeological artifacts by RF hydrogen low pressure plasma is a relatively new technique developed during the 1980s.
