Different Areas Buried The Relationship Between The Environment, Soil Characteristics And The Unearthed Bronze Corrosion

In this thesis, the in-depth study of the relationship between the unearthed bronze and the soil environment in different regions is based on the multi-disciplines analysis, such as chemical, metal corrosion science, soil corrosion, geochemistry, statistics and many other analysis methods. By the use of scanning electron microscopy and plasma mass spectrometry method of bronze corrosion and soil analysis, we can compare the corrosion and the bronze in the soil constant elements, trace elements . We can deal with a large amount of datum by using statistical methods to identify some sort of firm, objective, clear link in these complex systems.Through the analysis of experimental results, we find soil PH values of the analysis in five regions: the soil PH values of the Guanzhong regions and Northern Shaanxi Province are neutral, and the soil PH values of Gansu and Sichuan regions are partial alkaline. The more alkaline of the soil is, the more serious corrosion on the bronze. Therefore, the bronze buried in Gansu and Sichuan regions corrode easily and the rusty exchange with soil ion more frequently.The change of trace elements produced in corrosion of the five regions and the trace elements of the soil in buried place are concord in the basic line. However, the corrosion product in those regions and the most changeable trace elements of its buried soil environment are significantly different. Using factor analysis, in contrast with bronze corrosion product of the trace elements and parcel of trace elements in soil, the result is that a large number of precision measurements could be able to better reflect the bronze unearthed information, discriminate trace elements and the coupling between the buried areas relations basically. The analysis of trace elements can be used as a site unearthed bronze discriminate method.By anglicizing bronze rusty and elemental of the soil environment, according to the soil characteristics, bronze corrosion characteristics of the various kinds of information provided, we could judge the relationship between bronze rusty and buried soil, providing a method to discriminate geographical features of unearthed bronze.
