| Abstract |
Despite several studies on Mg-Ca alloys as bone implants, the understanding of its early degradation in the first hours of immersion is still lacking. To overcome this gap, advanced localized electrochemical techniques were used to study the corrosion onset of Mg-2Ca alloy 2 h upon immersion. The presence of the nobler beta-phase induced Mg dissolution from the matrix, an event supporting the positive response of osteoblast stem cells. This, together with apatite precipitation within the corrosion layer highlights the potential of Mg-2Ca for bone im-plants. The data gathered in this work contribute to tailoring the design of new Mg-Ca alloys. |
