Abstract
In this study, sodium salts of saturated linear carboxylic acids with the general formula CH3(CH2) n-2COONa (n = 14, 18)-labeled NaC14 and NaC18-were used to inhibit the corrosion of metallic lead via the development of protective coatings for lead heritage objects. The salts were dissolved in water/ethanol 1:1 (V/V) mixture at 50 A degrees C to increase their solubility, and the coatings were formed by immersing lead samples in the resulted solutions for 24 h. The coatings were characterized by scanning electron microscopy, Fourier transform infrared spectroscopy, X-ray diffraction, and X-ray photoelectron spectroscopy. A hydrophobic layer of lead carboxylates appeared to form on the metal surface, and its corrosion inhibition properties were examined by linear sweep voltammetry and electrochemical impedance spectroscopy in a corrosive solution simulating the environment of museums with uncontrolled conditions. The lead carboxylates formed a protective barrier that inhibited further lead corrosion.
