Microstructure design for biodegradable magnesium alloys based on biocorrosion behavior by macroscopic and quasi-in-situ EBSD observations
Source abstract
Abstract
The influence of alloying elements, grain size and orientation on biocorrosion resistance of Mg-2.1Nd-0.2Zn-0.5Zr (wt.%) were studied by immersion, electrochemical and quasi-in-situ electron back-scattering diffraction tests, to give a better microstructure design. The corrosion rate of this alloy is lower than that of pure Mg due to the smaller grain size and the presence of alloying elements in the corrosion layer. Preparation of samples with an average grain size smaller than 10 µm and weakening basal texture was recommended. These results are useful for uncovering the corrosion behavior of JDBM alloys and pure Mg, and designing microstructures for biodegradable implants.
