The Anodic Behavior of Manganese Silicide-Germanides in Aqueous Sodium Sulfate Solutions: The Effect of the Germanium Content
摘要
Abstract
The electrochemical behavior of manganese silicide-germanides with different ratios of germanium and silicon is studied using the methods of voltammetry and impedance spectroscopy in 0.5 M aqueous sodium sulfate solution. It is shown that the oxidation stability of materials decreases with an increase in the ratio of germanium, which, unlike silicon, is incapable of forming a layer of stable oxides on the material surface.
