Study of hydrogen/argon RF plasma used for brass corrosion removal

miscellaneous

English

Removal of corrosion products is based on plasmachemical reduction of corrosion layers by radio-frequency (RF) low pressure hydrogen/argon plasma. The influence of this process on corroded brass samples was investigated. OH radicals formed during this process were measured by optical emission spectroscopy (OES); simultaneously, sample temperature was measured by a thermocouple placed inside the objects. The SEM/EDS analyses of corroded and treated samples were performed. The applied plasma was monitored by OES and electron concentrations were estimated from H-beta spectral line profiles.
