金属间相 Mg2Al3 以块体形式合成，以便进行电化学表征。极化测试在 0.01 M NaCl 的 pH 范围 2-10 中进行，这与 Mg2Al3 相填充铝合金（即 5xxx 系列）的情况相关。 Mg2Al3 能够维持高溶解速率，但这取决于 pH 值。因此，报告了 E-pH 空间上持续的电流范围，并且通常用于协调其他工作中的局部腐蚀或腐蚀模型原料。 (C) 2013 Elsevier Ltd. 保留所有权利。
The intermetallic phase Mg2Al3 was synthesised in bulk form to permit electrochemical characterisation. Polarisation testing was performed in 0.01 M NaCl across the pH range of 2-10, which is relevant to instances where the Mg2Al3 phase populates Al-alloys (i.e. 5xxx series). Mg2Al3 is capable of sustaining high dissolution rates, but this is pH dependent. As such, the range of currents sustained over the E-pH space are reported and are of general use for reconciling localised corrosion or corrosion model feedstock in other works.
