摘要

圣卡罗-博罗梅奥巨像因其尺寸巨大而得名 "圣卡洛内",它为研究大气腐蚀对历史铜片上铜绿形成的长期影响提供了一个独特的机会。雕塑的巨大尺寸、复杂的几何形状、游客的直接互动以及暴露条件产生了不同的微气候。这项研究的目的是了解这些微气候如何以及在多大程度上影响铜锈的形成。研究结果表明,微气候在铜锈形成过程中起着关键作用:在暴露于雨水中的外表面,主要成分是铜绿辉铜矿,而在有遮蔽的内表面则发现了更多种类的腐蚀产物,如鹿角石、阿塔卡米石、草酸铜、posnjakite 和角闪石。

The Effect of Exposure Condition on the Composition of the Corrosion Layers of the San Carlone of Arona
The Colossus of San Carlo Borromeo, named San Carlone for its large dimensions, represents a unique opportunity to study the long-term effects of atmospheric corrosion on patina formation on historic copper sheets. The sculpture’s large dimensions, complex geometry, direct visitor interaction, and exposure conditions generate different microclimates. The purpose of this study is to understand how and to what extent these microclimates affect the formation of the copper patinas. The results show that microclimates play a key role in patina formation: in external surfaces exposed to rain, the main constituent is brochantite, whereas a wider variety of corrosion products have been found in sheltered and internal surfaces, such as antlerite, atacamite, copper oxalate, posnjakite, and anglesite.
