In vitro biodegradability of Mg–2Gd–xZn alloys with different Zn contents and solution treatments
This study aims to investigate the addition of Zn on the corrosion property and cytocompatibility of Mg–2Gd– x Zn ( x = 0, 3, 4 and 5; wt%) alloys, which were prepared by gravity permanent mold casting and solution treatment, respectively. The results show that the intermetallic phases of these ter...

. The content of secondary phases as well as the grain size is greatly dependent on the Zn addition. Compared to the binary Mg–2Gd alloy, the corrosion resistance of the most ternary alloys is significantly improved. Furthermore, the in vitro cell culture study demonstrates the potential cytocompatibility of the developed ternary alloys. It indicates that a series of Mg–2Gd–
