本powerpoint演示文稿首先简要概述了电偶腐蚀和碱度缓解理论 通过缓冲或 有助于形成保护性的 管秤。研究目的是:在以下条件下重现这一趋势: 受控环境； 确定是否存在“最佳坏的” 碱度；和 研究这种趋势的机制- 阳极的pH值， 阳极处的氯化物浓度，以及 具有导电性的电流。第一部分涉及倾倒和填充罐测试。第二部分涉及使用电化学测试电池 检查传导效应。包括数字。

This powerpoint presentation begins by providing a brief overview of galvanic corrosion and the theory of alkalinity mitigating corrosion by acting as a buffer or by contributing to formation of protective pipe scale. Study objectives were to: reproduce this trend under controlled circumstances; determine if there is an "optimally bad" amount of alkalinity; and, examine mechanisms for the trend - pH at anode, chloride concentration at anode, and galvanic current with conductivity. Part I involved dump and fill jar testing. Part II involved using a electrochemical test cell to examine conductivity effect. Includes figures.
