Research demonstrates improved mechanical properties and safety for Mg-Zn-Ga alloys in medical implants, suggesting further clinical trials.
The effect of hot extrusion on the mechanical and corrosion properties of alloys of the Mg-Zn-Ga system for medical purposes has been studied. It is shown that the Mg4Zn4Ga alloy has a favorable level of mechanical properties (σy = 343 MPa, σb = 256 MPa, δ = 14%) and a controlled corrosion rate (0.4 mm / year). The low cytotoxicity of the Mg4Zn4Ga alloy, determined in accordance with GOST R ISO 10993.5-99, makes possible to recommend it for further clinical trials in vivo and the manufacture of medical implants.
