| Abstract Scope |
The poor corrosion resistance of magnesium (Mg) is one of the main problems that restrict its large-scale application. In this paper, Fe-based metallic glass layer was prepared on the surface of the magnesium substrate by using the selective laser melting (SLM) technique and an Fe-based metallic glass powder. The layers and the substrate formed a good mechanical bond, and it maintained amorphous state after laser melting. The corrosion rate of the substrate Mg was reduced from 0.89 mm/a to 0.11 mm/a.The surface wettability of the metallic glass layers were also better than that of the magnesium substrate, which was conducive to the adhesion of cells on the surface of the metallic glass. Cell toxicity test experiments showed that the degradation products of metallic glass were not toxic to cells. This new treatment method provides a solution for improving the corrosion resistance and mechanical performance of Mg and Mg alloys. |
