The effect of rare earth element additions on the corrosion behaviour of magnesium alloy AZ91E

Research output: Chapter in Book/Report/Conference proceedingConference PaperResearchpeer-review


In the present communication the impact of precise rare earth (RE) elemental additions, such as Ce, La and Nd, on the corrosion of magnesium alloy AZ91 is explored. This investigation was undertaken in an attempt to assess whether the corrosion rate of AZ91 can be favourably altered as a result of engineering the rate of the anodic and cathodic reactions upon the alloy. It was found that low levels of these RE additions are a means for imparting an improved corrosion resistance on AZ91 and this communication outlines the underlying mechanisms involved.
