Abstract
This study explores the impact of substrate roughness on the adsorption of calcareous films through electrodeposition on substrates with roughness values of 1.0 μm and 0.3 μm. Test specimens were systematically fabricated by varying the roughness, electrodeposition time, and applied current density. The morphology of the fabricated samples was analyzed using scanning electron microscopy, which provided insights into their crystal size and surface characteristics. The structural properties of the deposited films were elucidated using X-ray diffraction. The corrosion behavior was systematically investigated using electrochemical polarization and 3% NaCl immersion tests. Notably, the samples electrodeposited on substrates with higher roughness exhibited larger crystallite sizes than those electrodeposited on substrates with lower roughness. The immersion experiment revealed a decrease in corrosion progression with increasing deposition time and substrate roughness. These results agree well with the results of the electrochemical corrosion test.
