Corrosion of Mechanically Milled, Annealed, and Biocompatible Magnesium Alloys for Osteopathic Tissue Regeneration.: Adam Rutherford¹; Mark Atwater¹; Julian Tse Lop Kun¹; ¹Liberty University
    The ZX series of magnesium alloys demonstrates superior corrosion resistance compared to other biocompatible magnesium alloys. Research focuses on die cast samples. Thus, the process-structure-property analysis of mechanically milled and annealed samples of the ZX series of magnesium alloys is required to demonstrate the relationship between corrosion and porosity. Various magnesium alloys were alloyed using a SPEX high-energy ball mill, annealed in a furnace, and underwent corrosion testing in simulated body fluid. A magnesium alloy that demonstrates exceptional corrosion resistance while retaining biocompatibility is essential to moving magnesium into the medical field of osteopathic implants. Porous magnesium alloys act as a scaffolding for the bone matrix to regrow. Magnesium implants have the ability to dissolve and avoid photoporation removal surgeries. The production of porous Mg alloys by powder metal processing also presents unique possibilities for alloy development that will be discussed in context with other methods.
