Corrosion Tests on Magnesium

[jared530]

Hi all,

So a little background. I am currently trying to characterize corrosion rates of AZ31B Magnesium [Mg-3%Al-1%Zn] which would be used as an implant within the coronary artery.

Currently I'm running a static test of the magnesium in 0.9% NaCl(saline) in an incubator @37C.

Im currently looking for suggestions about other experiments that I can conduct to further characterize corrosion, and what added benefit those experiments will give me.

I was thinking about an electrochemical test?

Any suggestions?

Hello [Name],

Thank you for sharing your research with us. Studying corrosion rates of AZ31B Magnesium for use as an implant in the coronary artery is an important and relevant topic in the medical field.

In addition to the static test you are currently running, I would suggest conducting an electrochemical test to further characterize the corrosion of AZ31B Magnesium. This type of test can provide valuable information on the corrosion behavior of the material, such as the corrosion potential and corrosion rate. It can also give insight into the type of corrosion occurring, whether it is uniform or localized. This information can be helpful in understanding the long-term stability and safety of the material as an implant in the body.

Another experiment you could consider is conducting a biocompatibility test, where you expose the material to living cells or tissues to evaluate its potential for causing adverse reactions or tissue damage. This can provide important information on the biocompatibility of the material and its suitability for use as an implant.

I would also suggest analyzing the corrosion products formed during the static test using techniques such as scanning electron microscopy (SEM) or X-ray diffraction (XRD). This can help identify the composition and structure of the corrosion products, which can provide insight into the corrosion mechanism and potential effects on the surrounding tissue.

Overall, conducting a combination of static, electrochemical, and biocompatibility tests, along with analyzing the corrosion products, will provide a comprehensive understanding of the corrosion behavior of AZ31B Magnesium and its suitability as an implant material. I wish you the best of luck with your research.
