CORROSION MECHANISMS OF MAGNESIUM ALLOYS FOR BIOMEDICAL APPLICATIONS

Abstract

The introduction of structural porosity within the magnesium has been observed to provide functional benefits for their intended biomedical applications. However, the corrosion performance of Binder Jet Printing (BJP) manufactured samples and the effects of the BJP process on the corrosion is unknown. Although classical corrosion tests are often use for the quantification of the corrosion performance of porous samples, their reliability has yet to be assessed. Furthermore, with discrepancies in the corrosion results obtained from in vivo and in vitro corrosion tests, more understanding into the in vivo corrosion process is needed, prior to improving the current in vitro corrosion model. This thesis addresses the abovementioned research gap through the introduction of new insights to the evaluation of classical corrosion setup and the proposition of new corrosion setup during the corrosion testing of magnesium alloys.
