| Abstract Scope |
In this study, the effect of different forms of a bioresorbable Mg66Zn30Ca4 alloy on the mechanical performance evolution was investigated after immersion in a physiologically relevant liquid. Different cooling rates were applied to control the structure of cylindrical rod samples under a single process of induction melting and suction casting into a water-cooled copper mold. Cooling naturally in the graphite crucible was also utilised to form a fully crystalline sample, due to the slow cooling rate. The samples were immersed in phosphate-buffered saline (PBS) at 37°C for several weeks, with commercial Mg alloy WE43 as the reference. The as-cast Mg66Zn30Ca4 with different levels of amorphous structure showed a higher compressive strength compared to the fully crystalline alloy and WE43. However, although the dissolution rate of the amorphous sample is the lowest among others, all of the Mg66Zn30Ca4 samples lost their strength after immersion, unlike WE43, which remained stable. |
