铜在自然环境中的腐蚀研究

The Research of Copper Corrosion in Natural Environment

介绍了目前国内外有关铜及铜合金在天然和模拟的大气环境、海水环境、土壤环境及微生物环境中的腐蚀研究成果,研究表明:铜在含氯离子的环境中更易发生腐蚀,并且单相铜合金比多相铜合金耐腐蚀性更好,为一些铜器的修复提供了理论依据,也提出了一些防腐蚀的方法,最后展望了铜腐蚀的研究趋势。

This paper presentes the research results of the corrosion situation of copper and copper alloys in the exposed and simulation of atmospheric environment,marine environment,soil environment,and microbial environment at home and abroad. It shows that copper tend to occur corrosion in the soil with chlorine content,and single-phase copper alloys have better corrosion resistance than that of multi-phase copper alloys. At the same time,it provides a theoretical basis for the restoration of some bronzes,and offered some anti-corrosion measures. Finally,it makes the prospect of the research trends in copper corrosion.
