Original Abstract

An effective and fast way of restoration and preservation of archeological artifacts is described. The process is based on using RF low-pressure hydrogen plasma in which the artifacts are treated for several tens of minutes. It proves that both hydrogen atom reduction and thermal decomposition are important. Temperature depends on used regime (continual or pulsed). Our results show that pulsed regime can be effectively applied in the corrosion removal process. The value of integral intensity of OH radicals measured by OES monitors the reduction process in plasma.
