Net ZRA galvanic current density recorded over 24 h for the flat galvanic geometric array where solid lines represent the current for AA7050 electrodes and dotted lines represent the current from Type 316 stainless steel electrodes. The key at the bottom shows the position of each wire in the array. The CMEA was exposed to a 0.6 M NaCl solution with 70 μm thin film at 98% RH at 23°C.
