“…For this purpose, BMGs have recently attracted much attention for biomedical applications. BMGs such as Ti-based [1][2][3], Zr-based [4], Mg-based [5,6], and Ca-based [7] are popular in the biomedical field. Ti-based and Zr-based BMGs are almost impervious to corrosion in the human body; hence they are suitable for permanent implant.…”

Mg and its alloys have attracted much attention recently as a biomaterial due to their excellent biocompatibility, similar mechanical properties to bone and biodegradability. However, the rapid degradation proved to be challenging to act as an implant. To improve the corrosion resistance and overcome rapid degradation of Mg-based alloys, researchers have been working on the synthesis of Mg-based bulk metallic glasses (BMGs). The first research on Mg-Cu-Y BMG was conducted by Inoue in 1991. Since then, Mg-based BMGs with different systems have been developed. Compared to the crystalline metallic Mg-based implants, the structure of Mg-based BMGs without any regular pattern offers low corrosion reactivity and increase passivity. Mg-based BMGs exhibit a good combination of biological, mechanical and corrosion properties and ease of fabrication. Thus, Mg-based BMGs can be considered an efficient candidate in the biomedical field.

“…Most of the existing works have been carried out by selecting the composition that can form metallic glass with a large D c [26][27][28][29][30][31][32][33][34], while research on metallic glass with a small D c is still rarely reported. If a fourth component is added into the aforementioned compositions, the changes in the structure of amorphous matrix and mechanical properties of the alloys are worth noting.…”

Mg‒Zn‒Ca metallic glasses are regarded as promising biodegradable materials. Previous studies on this alloy system have mostly focused on the composition regions with a large critical size (Dc) for the formation of metallic glasses, while this paper investigates the composition regions with a small Dc, which has been overlooked by researchers for a long time. The effects of the addition of Ag, Nd, and Yb elements on the microstructure and mechanical properties of Mg‒Zn‒Ca metallic glasses were studied. It was found that the Mg‒Zn‒Ca metallic glass exhibits a single and uniform amorphous structure with a compressive strength of 590 MPa. After the addition of a small amount of Ag into the alloy, the amorphous matrix is retained and new precipitate phases that lead to the decrease of the compressive strength are formed. The addition of the rare earth elements Nd and Yb changes the microstructure from a single amorphous matrix to a large number of quasicrystal phases, which results in an increase in compressive strength. The compressive strength of the Mg‒Zn‒Ca‒Yb alloy increases to 606.2 MPa due to the formation of multi-layered swirling solidified structure and a large number of small quasicrystals with high microhardness. Moreover, this study can be considered as a useful supplement to the existing studies on the Mg‒Zn‒Ca alloy system; it also provides new ideas for designing the microstructure and spatial structure of quasicrystal containing alloys with high performances.

“…The magnesium composites based on Mg-4Y-5.5Dy-0.5Zr alloy with 5 wt.% 45S5 Bioglass or 5 wt.% 45S5 Bioglass and 1 wt.% Ag addition modified with MgF 2 exhibit better biocompatibility in comparison to base Mg material. Additionally, different surface modification treatments could be proposed, attractive for their possible improvements of the corrosion resistance and biocompatibility of the magnesium-based materials [23,24]. Based on the previous research, bulk and surface treatment relations were applied and combined in this paper to maximize the effect of property enhancement obtained independently from the composition, the structure, as well as the surface treatment procedure.…”

Paper presents study on the hydrothermal treatment for hydroxyapatite layer formation on the different biodegradable Mg-substrates. The evaluation of corrosion resistance in Ringer’s solution and contact angle measurements in glycerol were performed. Alloys and composites substrates obtained by mechanical alloying and powder metallurgy route are characterized by submicron range microstructure, which is responsible for further surface processing characteristic. Hydrothermal treatment in Ca-EDTA (ethylenediaminetetraacetic acid calcium disodium salt) led to formation of hydroxyapatite layers, which improves both the corrosion resistance and surface wetting properties compared to microcrystalline magnesium.
