摘要

摘要本研究的目的是比较铜在不同膨润土浆料中的腐蚀性能。铜线圈样品暴露在膨润土BaM, Rokle, B75, G2M, Voltex, Sabenil的浆液中。试验在实验室温度的手套箱中厌氧条件下进行，持续时间为1至4个月。通过x射线衍射和质量损失对样品进行了评价。用离子色谱法和pH计对浆料的液体部分进行了分析。在所有的膨润土中，铜的电阻都很高。腐蚀速度为每年十分之几微米。孔隙溶液组成与腐蚀速率和腐蚀产物组成之间没有明显的关系。

Exposure tests of copper foils in a slurries of different bentonites

Abstract The goal of the study was to compare corrosion performance of copper in different bentonite slurries. Copper coil samples were exposed in a slurries of bentonites BaM, Rokle, B75, G2M, Voltex, Sabenil. The test was carried out under anaerobic conditions in glovebox at laboratory temperature for duration of one to four months. Samples were evaluated by means of X-ray diffraction and mass loss. Liquid parts of slurries were analysed by ion chromatography and pH meter. The resistance of copper in all studied bentonites was very high. Corrosion rates were in order of tenths of micrometers per year. No trend between pore solution composition and corrosion rate or composition of corrosion products was observed.
