On the effect of serum biomolecules on in-vitro corrosion of pure Mg and a novel bio-compatible dilute Mg alloy

<p>Biocorrosion of Mg is an important topic in the context of resorbable implant applications. This thesis investigates the role of serum biomolecules on corrosion of pure Mg and a dilute Mg-Zn-Ca alloy in in-vitro conditions. It has been identified that synergistic interactions between phosphate and calcium ions play a major role in controlling Mg biocorrosion. The presence of calcium in the alloy and/or the solution aids formation of a protective barrier against corrosion. The effect of extrusion on the corrosion of the dilute Mg-Zn-Ca alloy is also investigated and discussed.</p>
