Bronze artifacts in a buried condition start to be corroded by chloride oxygen, and underground water in soil. Excavated artifacts exhibits high possibility to get a bronze disease, especially Bronze artifacts should be stabilized to protect its surface. B.T.A(Benzotriazole) is the most generally used corrosion inhibitor for conservation treatment of bronze artifacts. However, B.T.A is not only weak for acidic condition but also harmful for human body. There was a large number of research to compensate these weak points, but none of these weren't applied for cultural heritages. Therefore, a study on the capability of modern corrosion inhibitor was performed for conservation of bronze artifacts. The samples made of bronzes, were processed into two groups. One was non-corroded group and the other was corroded group, and then, treated for conservation by chemicals. B.T.A, Cysteine, A.M.T, T.T.A were selected for this study, because they have shown a capability to protect bronze materials. The experiments were carried out by surface observation(optical microscope, SEM, α-STEP), chromaticity and glossiness measurement, and corrosion test to figure out corrosion velocity of bronze artifacts. Also corrosion resistance were tested by EIS. According to the observation of the artifacts by naked eyes, most of the samples were changed its color a little and the surfaces were stabilized by the chemical inhibitors. Cysteine treatment showed little difference in chronominance between non-corroded samples and corroded ones. Among the inhibitor treated samples, amino-merocapto-thiodiazole treated one showed the smallest differences in glossiness. Accelerating corrosion testing, impedance test after B.T.A and cysteine treatment showed the slowest corrosion velocity and excellent anti-corrosion effectiveness. As the conclusion for the comparison of the capability of corrosion inhibitors to conserve bronze artifacts, B.T.A and cysteine showed the best performance in tests. Cysteine is non-toxic and good corrosion inhibitor that contain, in addition to the amino group the -SH group, which has a strong affinity for copper. Consequently, cysteine would be a good alternative to conserve of bronze artifacts.
