Abstract
|
Magnesium is known as a suitable biological material because of its biocompatibility and biodegradability. The most important limitation of magnesium and its alloys is their poor corrosion resistance. Having a standard electrochemical potential of -2.38 V, magnesium and its alloys are considered to be the most anodic structural metal compared to the standard hydrogen electrode. Poor corrosion performance of magnesium and its alloys has resulted in a reduction in their chemical stability as well as limited use in corrosive media. One solution to overcome this obstacle is surface modification of these alloys. A variety of coating methods have been studied to provide protection for magnesium and its alloys against corrosion, including PEO. An important parameter in this process is chemical composition of the electrolyte.
