Abstract
The conjoint application of the voltammetry of immobilized particles (VIMP) methodology and the Mott-Schottky analysis (MS) of impedance data to studying metal corrosion patinas is described. The study is applied to copper and bronze objects exploiting the semiconducting character of cuprite and other copper corrosion products. A simplified theoretical modeling of MS analysis at microparticulate deposits extracted from metal corrosion layers attached to graphite electrodes is provided. The proposed model compensates for the disturbing effect of the regions of the basal electrode directly exposed to the electrolyte. Alternative models accounting for the variation of the density of charge carriers with depth are tested as well as the correlation between VIMP and MS data with reasonably satisfactory results.
本文介绍了固定颗粒伏安法（VIMP）和阻抗数据莫特-肖特基分析法（MS）在研究金属腐蚀铜绿的联合应用。该研究利用铜绿石和其他铜腐蚀产物的半导体特性，将其应用于铜和青铜物体。本文提供了一个简化的 MS 分析理论模型，用于分析从附着在石墨电极上的金属腐蚀层中提取的微粒沉积物。提出的模型补偿了直接暴露在电解液中的基极区域的干扰效应。还测试了电荷载体密度随深度变化的其他模型，以及 VIMP 和 MS 数据之间的相关性，结果相当令人满意。
