Abstract
AbstractCompared with traditional magnesium alloys, magnesium‐based metallic glasses exhibit favorable properties, making them potential materials for clinical implants. In this work, to develop magnesium‐based metallic glasses suitable for different degradation requirements, the effects of different structures of Mg–Zn–Ca–Cu alloys on their corrosion resistance were investigated. Mg66Zn29.5Ca4Cu0.5 metallic glasses were prepared by copper mold injection, and the alloys were heat treated at 90°C, 160°C, 230°C, and 270°C. The phase composition was determined by X‐ray diffraction, and electrochemical tests and hydrogen evolution experiments were carried out in a simulated liquid at 37°C. The results show that the corrosion resistance of the alloy is seriously affected by its microstructure.
