摘要

在 10 % PEG-200 溶液中对摩洛哥 "KASBA-OUDAYA "遗址出土的铁木复合考古物品进行了电化学和生物分析。由于采用了拟议的钢-木配置，因此可以对钢与木材的结合进行电化学测量，并通过扫描电子显微镜对钢-木界面进行自然老化试验后的表面特征进行分析。摩尔法和奈菲尔法可以测定氯离子和硫酸根离子。生物研究则通过分离和计数菌株来确保。研究结果表明，PEG-200 溶液中木材的存在降低了溶液的 pH 值，加速了钢的腐蚀。在界面上，我们观察到点状腐蚀区的发展。此外，PEG-200 溶液还为微生物的繁殖提供了有利环境。

Long-term electrochemical and biological study of archaeological iron-wood composite impregnated with 10 % PEG-200 solution

Electrochemical and biological analyzes were carried out on iron-wood composite archaeological objects from the “KASBA-OUDAYA” site in Morocco in 10 % PEG-200 solutions. Electrochemical measurements of steel combined with wood were made possible thanks to a proposed steel-wood configuration, with characterization of the surfaces after natural aging tests focused on the steel-wood interface by scanning electron microscope. The Mohr and Nephelometric method allow the determination of chloride and sulfate ions. While the biological study is ensured by isolation and enumeration of strains. The results revealed that the presence of wood in the PEG-200 solution decreased the pH of the solution and accelerated corrosion of steel. At the interface, we observe the development of pitting corrosion zones. In addition, PEG-200 solutions constitute a favorable environment for the proliferation of microorganisms.
