Effect of Plasmachemical Treatment on Corrosion Layers of Iron

Popis výsledku v původním jazyce

Application of plasmas is a new way of effective and fast treatment leading to conservation of metallic corroded objects. Removal of corrosion products is based on plasmachemical reduction of corrosion layers by radio-frequency (RF) low pressure hydrogenplasma. Influence of this process on corroded iron samples was investigated. OH radicals formed during this process were measured by optical emission spectroscopy; simultaneously, sample temperature was measured by a thermocouple placed inside the objects. The value of OH radical integral intensity represented quantitative ablation of oxygen from a corrosion layer. Sample temperature was an important indicator of sample protection against metallographic changes. It was proved that both hydrogen atom reduction and thermal decomposition were employed in the removal process. The XRD and SEM/EDX analyses of corroded and treated samples were done.
