The Novel Paste Electrolyte Measurement Cell for EIS Testing the Surface Protection on Bronze
The data include the results of measurements of the impedance spectrum of: - Bronze (Figure 3 a) and Bronze with sulfide patina and two coating layers (Figure 3 b) in 3.5% aqueous sodium chloride solution, tap water and paste electrolyte. - Sulfide patinated bronze with one (1L), two (2L) and three coating layers (3L) (Figure 5a). - The four types of artificial patina on bronze without (Figure 6 a) and with (Figure 6 b) two coating layers. - Artificial sulfide patina on bronze with a single coating that has been mechanically damaged (Figure 7 a). - Artificial sulfide patina on bronze which has been mechanically damaged (Figure 8 a) - Bronze coins in the untouched state (Figure 9 a) and with a single layer of coating (Figure 9b).
