Corrosion Performance Of Nitrided Based Coating On AZ91 Mg Alloy In Hank’s Solution

The use of Magnesium alloys as bioresorsable metallic implant is interesting to study due to the properties of magnesium ions which can be found naturally in bone tissue as well as are essential to human metabolism. However,its fast degradation rate and excess of these ions in the body may cause und...
