| Abstract Scope |
Magnesium alloys are biodegradable in the human body; however, they have poor corrosion resistance. The addition of rare earth elements is an innovative method to improve the properties of magnesium alloys for biomedical implants. The effect of cerium in magnesium alloys must be studied to determine its effectiveness in increasing corrosion resistance. Mg-Zn-Ca-Ce alloys of various compositions were melted and cast. The castability of each alloy was determined using a hot tear mold with various diameter arms. The composition of each alloy was verified using EDS elemental analysis. Optical and scanning electron microscopy was conducted to obtain the composition of each sample surface. Compression testing was performed to determine mechanical properties. Methods used for corrosion testing included placing samples in Ringer’s solution and completing a hydrogen evolution analysis. It was determined that samples with up to 0.2 weight percent cerium had the highest corrosion resistance. |
