Complications occur in orthopedic surgery. Corrosion of magnesium W4 alloy was investigated in vitro by electrochemical methods in solutions replicating the body's environment. To control the biodegradation of titanium and magnesium implants, bio active PEO coatings are essential for biomedical implants.
Magnesium (Mg) for biodegradable medical implant devices are limited by fast degradation rates of Mg. The study presents alloy design and thermomechancial processing to optimize mechanical and biological properties of a new proprietary Mg alloy. Corrosion profiles were evaluated by in vitro and in vivo studies.
AZ31 (UNS M11311) is a wrought magnesium alloy used in aerospace and automotive applications. In this work, KOH-based electrolytes were used to study the corrosion behavior of AZ31 alloy in highly alkaline environment. The effect of dopants and exposure time on pit initiation was studied via optical and scanning electron microscopy.
