Original Abstract
The aim of this work is application of low-temperature low-pressure hydrogen plasma on artificially prepared corrosion layers, so called plasma chemical reduction. It is necessary using samples with artificially prepared corrosion layers because it is impossible use the real artifacts for fundamental research. Formation of the corrosion layers on the bronze samples took place in concentrated hydrochloric acid vapors with addition of sand. The radio-frequency hydrogen plasma was generated in the flowing regime at pressure of 100 Pa. It was chosen different values of delivery power and different discharge modes: the continuous or the pulsed. By combination of delivery power and mode factors we selected two values of effective power. Process of plasma chemical reduction was monitored by optical emission spectroscopy (OES) and simultaneously the sample temperature was measured. Rotational temperatures were calculated from OH radicals spectra. The changes in the structure and elemental composition were made using scanning electron microscopy (SEM) and energy dispersive x-ray analysis (EDX).
