Originální abstrakt

New efficacious way of restoration and preservation of metal archaeological artifacts is described. This method is based on generation of reactive atomic hydrogen in low pressure RF hydrogen plasma discharge. Atomic hydrogen reacts with oxygen from corrosion layers of sample and forms OH radical. The value of integral intensity of OH radicals represents quantitative ablation of oxygen from corrosion layer. Another monitored magnitude was temperature of samples. Sample temperature sample is very significant indicator for protection sample against metallographic changes of metal bulk material and therefore damage of samples. We proved that the corroded sample became much less warm in pulsed than in continuous regime. Thus there is no risk of metallographic changes or damage of sample in pulsed regime.
