Abstract
ABSTRACT The micromorphology and composition of three pieces of ancient celadon with various degrees of corrosion salvaged from Dalian Island, Pingtan County of East China's Fujian Province were analyzed. The results indicate that there were black corrosion products with a high content of Fe and Mn and white crystals with high concentrations of Ca and Mg on the surfaces of the samples. The black corrosion products infiltrated into the interior along the cracks on the sample surfaces, producing corrosion products mainly composed of FeOOH and MnO2. Meanwhile, there were white crystals containing MgCa(CO3)2 gathering on the black corrosion surface. Subsequently, the attachment of a biological carbon film containing proteins and polysaccharides in the corrosion area was determined by Fourier transform infrared spectroscopy and steady state and transient fluorescence. It is speculated that the existence of a bio-film and the presence of Fe and Mn oxides is related to the microbial corrosion and mineralization of iron bacteria in the marine environment. In this paper, through the analysis of the corrosion products of the effluent celadons as well as the study of iron bacterial biological corrosion and biomineralization, the corrosion model is explained and established so as to clarify the microbial corrosion mechanism of celadon ceramics retrieved from the seabed.
