Influence of the Sandy Incrustations on the Plasma Chemical Corrosion Removal from Bronze

Popis výsledku v původním jazyce

Treatment of bronze samples by low-temperature, low-pressure hydrogen plasma was performed. This process is called plasmachemical reduction. The bronze blocks of dimension 50x15x5 mm3 were used for this study because there is impossible to use original objects for the comparative studies due to their uniqueness. A creation of model corrosion layer on the surface of each sample was the next step. Model corrosion layers were created in the vapours of concentrated hydrochloric acid. The prepared model corrosion layers were exposed to the effect of hydrogen plasma at pressure of 150-170 Pa. It was chosen different experimental conditions for each sample. Plasma treatment monitoring was provided by optical emission spectroscopy (OES). Rotational temperaturewas calculated from OES, the temperature of the sample that is a critical process parameter was measured by thermocouple placed inside the apparatus.
