Impact of pH and chloride content on the biodegradation of magnesium alloys for medical implants: An in vitro and phase-field study
S. Kovacevic, W. Ali, T. K. Mandal +2
The individual contributions of pH and chloride concentration to the corrosion kinetics of bioabsorbable magnesium (Mg) alloys remain unresolved despite their significant roles as…
Phase-field modeling of pitting and mechanically-assisted corrosion of Mg alloys for biomedical applications
S. Kovacevic, W. Ali, E. Martínez-Pañeda +1
A phase-field model is developed to simulate the corrosion of Mg alloys in body fluids. The model incorporates both Mg dissolution and the transport of Mg ions in solution, natural…
Bioabsorbable WE43 Mg alloy wires modified by continuous plasma-electrolytic oxidation for implant applications. Part I: processing, microstructure and mechanical properties
Wahaaj Ali, Muzi Li, Leon Tillmann +4
In our work, a novel processing strategy for the continuous fabrication and surface modification of wires from Magnesium alloy WE43 by means of plasma-electrolytic oxidation (PEO)…
Strength, corrosion resistance and cellular response of interfaces in bioresorbable poly-lactic acid/Mg fiber composites for orthopedic applications
Wahaaj Ali, Mónica Echeverry-Rendón, Alexander Kopp +2
The shear strength and the corrosion resistance of the fiber/matrix interface after immersion in simulated body fluid was studied in poly-lactic acid/Mg fiber composites. The shear…
