The focus of this study consists of examining how corrosion potential measurements can contribute in providing information on the effectiveness of storage and stabilization treatments of copper alloys in aqueous solutions. We report on the electrochemical behavior of artificial copper alloy coupons (covered or not with corrosion layers), simulating the behavior of real artifacts, immersed in sodium sesquicarbonate solutions. Particular attention is given to the transformation of the corrosion layer as a function of time. In addition, synchrotron radiation X-ray diffraction measurements are performed before and after the treatment in order to understand the reactions that take place during the immersion processes.
本研究的重点在于考察腐蚀电位测量如何有助于提供关于铜合金在水溶液中的储存和稳定化处理效果的信息。我们报告了模拟真实文物行为的人工铜合金试片(有无腐蚀层覆盖)浸入倍半碳酸钠溶液中的电化学行为。特别关注腐蚀层随时间的变化。此外,在处理前后进行同步辐射X射线衍射测量,以了解浸泡过程中发生的反应。
