Abstract
A method to form a metal matrix composite reinforced with eggshell (ES). The method includes preparing an ES powder, blending and milling the ES powder with at least one metal powder selected from the group consisting of magnesium (Mg), zirconium (Zr) to form a powder mixture, compacting and sintering the powder mixture to form the metal matrix composite. In addition, a Mg—Zr-ES metal matrix composite with improved corrosion resistance, having an amount of magnesium from 95 to 97 wt. %, an amount of zirconium from 1 to 2 wt. %, and an amount of ES from 1 to 4 wt. %, may be used for biomedical applications.
Claims16
A method to form a metal matrix composite reinforced with eggshell (ES), comprising:
- blending and milling at least one magnesium (Mg) powder and at least one zirconium (Zr) powder and at least one ES powder to form a powder mixture;
- compacting the powder mixture in a press to form a compacted powder mixture;
- and
- sintering the compacted powder mixture to form a composite matrix by making the compacted powder mixture coalesce into a solid or porous mass by heating it without complete liquifaction;
- wherein said Mg powder has a particle size in a range of 20 to 70 micrometers (μm);
- wherein said Zr powder has a particle size in a range of 20 to 60 μm;
- wherein after the sintering, the composite matrix comprises magnesium, zirconium, and ES;
- and
- wherein the amount of magnesium in the composite matrix is from 89.9 to 99.9 wt. %, the amount of zirconium in the composite matrix is from 0.1 to 10 wt. %, and the amount of ES in the composite matrix is from 0.1 to 10 wt. %.
