Diagnostic of Plasmachemical Removal of Complex Corrosion Layers from Metallic Surfaces

Popis výsledku v původním jazyce

Plasmachemical treatment of corrosion layers is a technique usually applied in the field of archaeological metallic artifacts conservation and restoration. The process is based on using low-pressure hydrogen plasma in which the artifacts are treated forseveral hours, usually in more steps. The diagnostics of this process was given for the oxide corrosion only where the OH radicals spectra and H atomic lines were observed. The real corrosion layers are much more complicated, they contain also the chlorine, amino, carbon, sulfate and other corrosion types. The complex corrosion layers on the copper samples were prepared in this study. Besides the hydrogen and OH radicals spectra the spectra of molecules containing nitrogen, carbon and oxygen were recorded as a function of the plasma treatment duration. These species are removed from the plasma faster than oxides and thus the monitoring of OH radicals spectra will be sufficient for the process monitoring in the cases when the oxide corro
