Plasma Chemical Reduction of Model Corrosion Brass Layer Prepared in Soil
Original language description
Samples corroded naturally more than two years in the soil in the vertical and horizontal positions, so the corrosion layers were the most similar to the corrosion layer of original archaeological artifacts. The samples were treated in the low pressure (150 Pa) in a hydrogen-argon gas mixture at mass flows of 30 sccm for hydrogen and 20 sccm for argon for 90 minutes. 13 samples were treated. The plasma power was 100, 200, 300, and 400 W in continuous and pulsed mode. Maximum sample temperature was set at 120 °C. The whole process was monitored by optical emission spectroscopy and the obtained data were used to calculate the relative intensity of OH radicals and rotational temperature. The results showed that the higher power had the greater maximum intensity of the OH radicals and rapidly degraded the corrosion layer. Corrosion layer was not completely removed during the reduction, but due to the reactions which occur in the plasma corrosion layer became brittle and after plasma chemical treatment can be removed easily.
