ABSTRACT

The hydrogen evolution process in the as-cast Mg-0.6Ca alloy was investigated using real-time optical imaging of the corroding surface. It was revealed that hydrogen evolved as large stable bubbles and continuous streams of tiny bubbles because of high localised current density. To the best of the author’s knowledge, this is the first attempt to characterise the hydrogen evolution behaviour of Mg-Ca binary alloy employing a mechanistic model based on real-time imaging.

使用实时成像阐明共晶 α-Mg 薄片和 α-Mg 基体之间的微电流耦合对 Mg-0.6Ca 二元合金析氢行为的作用

摘要

使用腐蚀表面的实时光学成像研究了铸态 Mg-0.6Ca 合金的析氢过程。结果表明，由于局部电流密度高，氢气会以稳定的大气泡和连续的微小气泡流的形式产生。据作者所知，这是首次尝试使用基于实时成像的机械模型来表征 Mg-Ca 二元合金的析氢行为。
