Development of a new protection methods based on a analysis of the corrosion mechanisms for metal cultural properties

从金属文化遗产的表层分析入手，提出了新的保护方法。使用金属文化属性是meiwa-gomonmegin，bunnseisshukinn，mameitagin和钢。这些金属文化属性是铜合金、银金合金和铁。表面产生氧化层，因此这些文化财产具有很高的耐腐蚀性。贵金属如Ag或Au富集层的存在对腐蚀有效。

From the surface layer analysis of metal cultural properties, new protection methods is developed. Using metal cultural properties is meiwa-gomonmegin, bunnseisshukinn, mameitagin and steel. These metal cultural properties are Cu-ally, Ag-Au alloy and iron. Oxide layer produced on the surface, and as a result, these cultural properties have a high corrosion resistance. Existence of noble metal such as Ag or Au rich layer has a effective for corrosion.
