摘要: Zinc-based alloys represent one of the most highly developed areas regarding biodegradable materials. Despite this, some general deficiencies such as cytotoxicity and poor mechanical properties (especially elongation), are not properly solved. In this work, a Zn-5Mg (5 wt.% Mg) composite material with tailored superior corrosion is prepared by powder metallurgy techniques. Pure Zn Mg mixed subsequently compacted extrusion at 200 °C an ratio 10. The final product possesses appropriate (tensile yield strength = 148 MPa, ultimate tensile 183 elongation 16%) decreased four times release in initial stage degradation compared to pure Zn, which can decrease effects therefore positively affect healing process.
